accidentally liking someone’s Facebook post is the worst, especially when you’re creeping on their profile. Rebecca and i investigated this last night. (ps if it matters, I liked/unliked her status via the Facebook mobile app.)
Chris asked me if this applies to Twitter tweet-favoriting, we tested it and it does not; notifications go through fast on that front. i just tested Instagram with Troy and that does NOT notify the person if you quickly unlike the post.
i need to form some sort of internet-stalking research taskforce.
