Unfollow people that do not follow you on Twitter

unfollow.js

/* Scroll to the bottom of https://twitter.com/following
Open the Console and run the following
*/

$('.ProfileCard-content').each(function(){var status = $(this).find('.FollowStatus').text();var unfollowButton = $(this).find('.user-actions-follow-button');if(status != 'follows you'){unfollowButton.click();}});

it doesn't work, unfollow every user

$('.ProfileCard-content').each(function(){
var status = $(this).find('.FollowStatus').text();
var unfollowButton = $(this).find('.user-actions-follow-button');
if(!status){unfollowButton.click();
}});

its works

This simple script to easily Follow | Unfollow Twitter Followers | Unfollowers at once works like a charm.

A post was created at forums.mozillazine.org's for troubleshooting sake's for a Linux user.

Hello,

It seems that from now on, Twitter is using a different code structure (as of July 2019).

Here is the code I made to make it work with the new Twitter web site:

/*
	Unfollow (stop following) those people who are not following you back on Twitter.
	
	This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).
	
	Instructions:
	1) The code may need to be modified depending on the language of your Twitter web site:
		* For English language web site, no modification needed.
		* For Spanish language web site, remember to set the variable 'LANGUAGE' to "ES".
		* For another language, remember to set the variable 'LANGUAGE' to that language and modify the 'WORDS' object to add the words in that language.
	2) Optionally, you can edit the 'SKIP_USERS' array to insert those users that you do not want to unfollow (even if they are not following you back).
	3) When the code is fine, on Twitter web site, go to the section where it shows all the people you are following (https://twitter.com/YOUR_USERNAME_HERE/following).
	4) Once there, open the JavaScript console (F12 key, normally), paste all the code there and press enter.
	5) Wait until you see it has finished. If something goes wrong, reload the page and repeat from the step 3 again.

Thank you very much. Any comments are welcome.

EDIT: code modified to improve reliability, accept more languages easily and added the option to skip users that we want to keep (those we do not want to unfollow).

Looks great. Nice work!

Hello again.

I edited the gist code to be able to either unfollow only non-follwers or unfollow everyone (depending on a parameter which can be modified), always with the option to skip (avoid unfollowing) those ones we want to keep.

Here is the code:

/*
	Unfollow (stop following) those people who are not following you back on Twitter (or unfollow everyone if desired).
	
	This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).

	2) Optionally, you can edit the 'SKIP_USERS' array to insert those users that you do not want to unfollow (even if they are not following you back).
	3) If you want to follow everyone (except the users in 'SKIP_USERS'), including those who are following you, just set the 'UNFOLLOW_FOLLOWERS' variable to 'true'.
	4) When the code is fine, on Twitter web site, go to the section where it shows all the people you are following (https://twitter.com/YOUR_USERNAME_HERE/following).
	5) Once there, open the JavaScript console (F12 key, normally), paste all the code there and press enter.

Thank you very much. Any comments are welcome.

Thanks so much, @jalbam - really amazing script there. I wonder if you could add a few extra things?
First of all, could we set a limit? For example, stop the script after it's unfollowed 100 or 200 (or user-defined) accounts?
And second, could we add an optional delay between the script unfollowing each account? Just in case Twitter doesn't like it?
Thanks!

Hello again,

Thank you for your comment,. In fact, those improvements were made already in the official gist but I did not publish the update here, sorry.

You can set a limit of total unfollow actions performed setting the 'MAXIMUM_UNFOLLOW_ACTIONS_TOTAL' variable with the desired number. You can also set a limit of unfollow actions performed per cycle (each call to the 'performUnfollow' function) setting the 'MAXIMUM_UNFOLLOW_ACTIONS_PER_CYCLE' variable with the desired number.

You can also set the milliseconds per cycle (each call to the 'performUnfollow' function) by modifying the 'MS_PER_CYCLE' variable.

So, for example, if you want to unfollow one person each second then you can set the 'MAXIMUM_UNFOLLOW_ACTIONS_PER_CYCLE' variable to 1 and the 'MS_PER_CYCLE' variable to 1000.

Here is the new code:

/*
	Unfollow (stop following) those people who are not following you back on Twitter (or unfollow everyone if desired).
	
	This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).
	
	Instructions:
	1) The code may need to be modified depending on the language of your Twitter web site:
		* For English language web site, no modification needed.
		* For Spanish language web site, remember to set the 'LANGUAGE' variable to "ES".
		* For another language, remember to set the 'LANGUAGE' variable to that language and modify the 'WORDS' object to add the words in that language.
	2) Optionally, you can edit the 'SKIP_USERS' array to insert those users that you do not want to unfollow (even if they are not following you back).
	3) If you want to follow everyone (except the users in 'SKIP_USERS'), including those who are following you, just set the 'UNFOLLOW_FOLLOWERS' variable to 'true'.
	4) You can set the milliseconds per cycle (each call to the 'performUnfollow' function) by modifying the 'MS_PER_CYCLE' variable.
	5) If desired, set a number to the 'MAXIMUM_UNFOLLOW_ACTIONS_PER_CYCLE' variable to establish a maximum of unfollow actions to perform for each cycle (each call to the 'performUnfollow' function). Set to null to have no limit.
	6) If desired, set a number to the 'MAXIMUM_UNFOLLOW_ACTIONS_TOTAL' variable to establish a maximum of unfollow actions to perform in total for all cycles (all calls to the 'performUnfollow' function). Set to null to have no limit.
	7) When the code is fine, on Twitter web site, go to the section where it shows all the people you are following (https://twitter.com/YOUR_USERNAME_HERE/following).
	8) Once there, open the JavaScript console (F12 key, normally), paste all the code there and press enter.
	9) Wait until you see it has finished. If something goes wrong or some users were not unfollowed, reload the page and repeat from the step 6 again.

This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).

Instructions:

1. The code may need to be modified depending on the language of your Twitter web site:
   • For English language web site, no modification needed.
   • For Spanish language web site, remember to set the 'LANGUAGE' variable to "ES".
   • For another language, remember to set the 'LANGUAGE' variable to that language and modify the 'WORDS' object to add the words in that language.
2. Optionally, you can edit the 'SKIP_USERS' array to insert those users that you do not want to unfollow (even if they are not following you back).
3. If you want to follow everyone (except the users in 'SKIP_USERS'), including those who are following you, just set the 'UNFOLLOW_FOLLOWERS' variable to true.
4. You can set the milliseconds per cycle (each call to the 'performUnfollow' function) by modifying the 'MS_PER_CYCLE' variable.
5. If desired, set a number to the 'MAXIMUM_UNFOLLOW_ACTIONS_PER_CYCLE' variable to establish a maximum of unfollow actions to perform for each cycle (each call to the 'performUnfollow' function). Set to null to have no limit.
6. If desired, set a number to the 'MAXIMUM_UNFOLLOW_ACTIONS_TOTAL' variable to establish a maximum of unfollow actions to perform in total for all cycles (all calls to the 'performUnfollow' function). Set to null to have no limit.
7. When the code is fine, on Twitter web site, go to the section where it shows all the people you are following (https://twitter.com/YOUR_USERNAME_HERE/following).
8. Once there, open the JavaScript console (F12 key, normally), paste all the code there and press enter.
9. Wait until you see it has finished. If something goes wrong or some users were not unfollowed, reload the page and repeat from the step 6 again.

NOTE: STILL NOT SURE ABOUT THE TEXT IN THE CONFIRMATION BUTTON FOR ENGLISH LANGUAGE. LET ME KNOW OR MODIFY IT BY YOURSELF TO THE CORRECT ONE IF NEEDED!

Thank you very much. Any comments are welcome.

Thanks so much, @jalbam - this script you've created is amazing. Thanks for keeping it updated. I'll reply to your main Gist now!

@jalbam You are awesome :)

Hello again,

Thank you for your comment,. In fact, those improvements were made already in the official gist but I did not publish the update here, sorry.

You can set a limit of total unfollow actions performed setting the 'MAXIMUM_UNFOLLOW_ACTIONS_TOTAL' variable with the desired number. You can also set a limit of unfollow actions performed per cycle (each call to the 'performUnfollow' function) setting the 'MAXIMUM_UNFOLLOW_ACTIONS_PER_CYCLE' variable with the desired number.

You can also set the milliseconds per cycle (each call to the 'performUnfollow' function) by modifying the 'MS_PER_CYCLE' variable.

So, for example, if you want to unfollow one person each second then you can set the 'MAXIMUM_UNFOLLOW_ACTIONS_PER_CYCLE' variable to 1 and the 'MS_PER_CYCLE' variable to 1000.

Here is the new code:

/*
	Unfollow (stop following) those people who are not following you back on Twitter (or unfollow everyone if desired).
	
	This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).
