Seems there was a data breach a while ago and the hacked accounts are mostly inactive ones, but just to be safe, change your password.

Edit: These started appearing only a few hours ago, and moderators are already erasing them! Hat's off to them for that quick response. They're still appearing, though. Some troll got booted from the FA Discord, presumably because they were trolling, and they're salty about it.
