Anime avatars are often a coin toss between (potential) comrade and chud, so it may be fun and maybe helpful to think about and share those in the place of that old bellwether for chuddery.
Mine is anyone with ".eth" as a suffix in their online name. I have yet to see a single person that does that that isn't a chud.
It may even be cheating, but seeing an actual cryptofascist cartoon "original NFT do not steal" is a pretty reliable red flag too.
EDIT: Oh yeah, I almost forgot.
What if you have the Zhuge Liang annotated version, and it's on the shelf next to your copy of Romance of the Three Kingdoms?
I'll allow it.
