Verbose update from the FA tech team:

Too long for alt text. Content is available on Fender's journal here: https://www.furaffinity.net/journal/10936501

TL;DR: FurAffinity is back up, attacker may have briefly engaged in email spoofing. Attacker did not (to their knowledge) ever have access to real FA emails or user data. You were logged out and should log back in.

As before, we don't know who the hacker is or how they did it. (See my misinfo post for more: https://dragon.style/@pyrex/113004484026364537)
