// paste this into javascript console on a twitter permalink status page (https://twitter.com/[user]/status/[id]) 
// this will make any tweet you retweet on that page also pin itself to your profile
// this is very laggy bc jquery sucks
// so i recommend opening your tweet in a new tab, pasting the code, retweeting, and then closing the tab
// also this only works on old twitter, not nu PWA twitter

// enjoi

// oh also
// this works because when you retweet a tweet, you get a tweet id
// this is not the original tweet's id, this is actually the id *of your retweet*
// for backwards compatibility reasons, twitter, despite displaying them differently, actually has retweets stored as normal tweets
// and these normal tweets are attributed to you
// so since it's a tweet, and it's attributed to you, the /i/tweet/pin api goes "well ok" and pins it bc it never checks if its a retweet
