It sounds more like the "Good Game Auto Blocker," [1] by that wonderful human being Randi "freebsdgirl" Harper [2]. It will block people on your Twitter account who are on a list of accounts believed to be associated with the #GamerGate movement, though it's known to have been overzealous at times, including an account operated by KFC in its lists [3] to much amusement. (This list seems to be generated by checking an account's followers to see if it follows the accounts of too many "leaders" or known pro-GG partisans.) In theory, there's nothing wrong with lists like these if they're just used for their intended purpose, but there's some fear that they might be used as industry hiring blacklists, as some have already proposed [4].

In short, if you're going to "troll" on Twitter (which includes sharing opinions others might not like) and end up on one of these lists, it might be best to do so strictly pseudonymously.
