Lemmygrad is tankies, which is exactly the point. You can't tell the difference between anarchists and the people who murdered them. The political compass exists to create that confusion, equating "libertarianism" (by which, they mean right wing "libertarianism") with the original definition of libertarian socialism.
Even the choice of "libertarianism" as a name was intentionally chosen to confuse things, to steal a word and destroy it's meaning. IIRC, Murray Newton Rothbar literally said that he was intentionally stealing the word "libertarian" for the right. The whole thing is about propaganda and confusion, and the political compass is part of that.
