Discord banned 8k users for posting benign grid images

> “When our staff reviewed and cleared those accounts, the same bug prevented the ban from being lifted automatically, so it just stayed in place,” Discord says.

It seems like a similar issue is affecting Twitter currently. People are being suspended for inauthentic behavior, they appeal, they get an email saying the appeal was accepted, and then, nothing, the account doesn't come back. Is there perhaps a third party moderation platform behind both of these services?

Imagine you suddenly getting banned after posting a picture of a chessboard
