The guy got banned because he came up and asked a question and the community couldn't answer. People told him to just ask in the right channel where all the questions are collected in order to prepare the dev weekly update where the team is (weekly) answering to all the important questions and concerns with details and profesionalism. The guy kept asking the, exact, same, question, for more than one hour, ending by saying since the devs weren't putting things his way, they were idiot and the project were worthless. This was plein and annoying fud, and if I were moderating there I couldn't have awaited one hour to kick him out and clear our space.
