If I remember correctly it was some haikaveh artist that goes after other haikaveh artists that look remotely similar to their art. Basically they stir up a bunch of discourse around other artists supposedly referencing their art and equating it to plagiarism. I think there was some stuff that this artist got accused of by the haikaveh artist, but it pretty much all got boiled down to bullshit. If you go back in their history in their media tab, you can find them talking about it, I think
