Use this to block all followers of someone encouraging harassment

block_all_followers_of.py

'''
This is a python script to block all followers of a particular user.

Here's what you have to do:

# Twitter Authorization

1. Go to apps.twitter.com
2. Click on Create New App
3. Fill in the stuff. None of it matters
4. Go to Keys and Access Tokens
5. Click on Create my access token
6. Copy the consumer key, consumer secret, access token, and access token secret
7. Paste them in the script (those first lines after the `import`s)


# Detective work stuff (not really)

Get the user accounts of people you want to block all followers of


# Python stuff

1. Open Terminal.app
2. Enter `pip install tweepy` and give it a few seconds
3. If it produces an error (a bunch of red text) use `sudo pip install tweepy`
4. Enter `python ` (don't forget the space!) (and don't hit return yet)
5. Drag this file to the Terminal window. Its path should be filled in
6. Hit return

It will take a while...

Every account that follows these suspicious accounts will be blocked by the user
who issued the API tokens. You can then export the list of blocked accounts 
(on twitter.com) and give it to someone else to import.


# Notes

If you have any problems you can tweet @tennabey (or DM me).
And if it's because of an error you should probably take a screenshot of the
Terminal window.

If you want to stop the script just hit Ctrl+C
