well to answer that question, I think Discord is the forum. However, if you are in his discord, and if you so much as peep anything that isn't in the positive to BrainDead, you are banned, muted, kicked out of the discord. His forum is purposely controlled to only allow comments that portray BD in a positive light. There was also the issue where BD deleted all the comments in Patreon during his 2 year hiatus so that anyone who wanted to subscribe wouldn't see all the history. The only place to complain to him is here. Even BrainDrop is a member, although I think he's completely ghosted his profile or goes by another pseudonym. He reads the complaints here or has someone report back to him because ever so often, he acknowledges the comments or tries to make some sly quips in his dev reports.
