So, the first kBin post was from an anarchist...

Is that on kbin? Or is that from Lemmy? Kbin isn't 4 years old AFAIK.

That's dessalines - the main dev of Lemmy.
The post is not from kbin (hover your cursor above the link you've marked red in your screenie and you'll see it's not "local" community).

He is not an anarchist. He is a known tankie.

It was a post on anarchism@lemmy.ml by user dessalines@lemmy.ml.

EDIT: I'd also add that dessalines is one of the Lemmy devs, so was probably a test post.

Okay, I guess I'm not as smart as I thought I was, but it has "anarchism" in the magazine name, and it didn't see anarchism as just havoc.
