How in the world is Arcane considered anime? It wasn't written or produced in Japan, nor does it have the anime style.

GP commenter never claimed it was. I imagine they recommended it based on what GGP commenter seems to like.

I think it's fair to say it's not anime, but if you were to recommend the show to someone and give a brief description or comparison, I think it definitely shares more stylistic elements with anime than it does with other cartoon media.
