Theymos accidentally[1] set everyone's activity to 1568 and everyone could have an avatar. It's fixed already though.

Okay thanks for letting me know, but shouldn't Theymos remove that avatar now?
He barely has time for the forum, I don't think he will manually remove it even if it was possible.
At any rate the avatars ,I think, will be removed any time an activity update is up and the user is online.
Yeah, he doesn't really have any reason to, lol.
No, I don't think it would be removed then. That is very unlikely. Had I uploaded an avatar when I joined (in 2013), even when it was disabled later it would still be there. So did all those accounts who had an avatar at that time. IIRC, there was even animated gifs, not sure if it is still there though.
Once it is uploaded it will stay unless the admin removes it.
