Yeah Meta's bots are well and truly stuck in the blackhole on this site at the moment. I have no idea what they're supposed to be doing, but in case they are using them for AI work I've just added a token multipler based on subnet totals so they can have some more fun. I might come up with some other fun response types for them too.
Meta bots are also problematic, as they seem to be quite buggy. But the volume was nowhere near the hundreds of bots from China :/
