I have an account to follow artists, mostly Japanese but some Westerners as well. I personally found it to be valuable, as there are some artists I've discovered that never use Pixiv or whatnot and other artists usually boost each other through retweets.

I make it a point to never follow artists that post more politics or personal drama than art. I don't care if it's a leftoid or a rightoid; their hot takes pollute my feed no matter the alignment and it becomes a giant retard magnet. If I wanted that shit, I'd dive in the algorithmic sewer that is the "For you" tab.
