We've needed to disable avatar uploads for users while we address a bug with the system. Your current avatars should continue to show, you just won't be able to change it.
There is no ETA on when the functionality will return, but it hopefully won't be too long.
Sounds like a cover story to me. I bet they are just trying to stop people from changing their avatars to ponies.
I wish they would. I can't open a single thread anymore without at least one pair of huge, creepy pony eyes gazing at me... dead eyes, yet aware... blind, yet all-seeing... of utter darkness yet... brightly-coloured... they're everywhere...
Actually, the bug is probably because of everyone changing to the pony avatars. All you ponies broke BGSF. I hope you are happy. Actually, you probably are. All this incessant happiness.
