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. 
A giant Romanian Fascist that grew out of Cutis Yarvin's circle in the early 2010s, and LARPs as embodying the aesthetic ideal of a Homeric Hero. Vaguely ridiculous like all fash but no less dangerous for all that. His thesis is the standard fash shit of "Eternal irrational struggle vs nature and man for domination is the purpose of life, etc, etc."
Basically, imagine if Evola had no talent and was a member of the 2016 era alt-right.
But "Moldbug" said his cult can't be fascist because he likes drugs too much and wants to seem high tech and hip and cool and with it. He even made "Urbit." You heard of it? Probably not, because you're not alt-right enough to understand!
