What are some of your favourite niche or hobby-based Lemmy instances, and which ones should be avoided at all costs?

Automod bugged out and banned me forever from reddit, i want to explore more Lemmy now but am not sure if Im missing anything good im not directly looking for--i am also kinda autistic and oblivious so if there are instances with a bad history or full of chuds or something a heads up would be swell
