Was banned from the Discord server without reason

I decided that I wanted to join the Halo Discord server to see updates on future games and progress on the MCC coming to pc. However, whenever I clicked the join link and was redirected to Discord i have discovered that the server was not there. After going back to chrome for another join link I could not get another as it said I was banned. If this is a mistake please fix it and if not, tell me as to why because I was banned under a second of joining. Edit: I should probably add my Discord name here, it is

Hello! I’ll be sending you a friend request on discord very shortly so we can get this sorted out :slight_smile:
