You were apparently permanently banned from their instance due to being toxic, and what you’re seeing in that screenshot are the individual communities mirroring the ban from the instance to the community level. What “toxic” consists of is really known only by the person who issued the ban, and whether or not you even care is really up to you. It could have been for something legitimate, or it could have been completely bogus, and I’m not going to scour your comment history to try to figure it out; chances are you know what you did, and if you don’t, it’s probably just some mod on a power trip, who knows?
