Not possible to join team events

Hello,
I still have access to Lichess and I am still Patreon supporter. However since a while I cannot join team events (in teams where I am member) and challenge games are not rated. Please let me know the reason. If it has something to do with cheating I am wondering why I have not received a message where I can refer do and can still play.

Mouse hover over your nick. It says "This account violated the Lichess Terms of Service". In most cases this is due to cheating. Means you can still play but you are only paired with other cheaters so at least you can find out who has the better engine.

Thanks for your quick feedback. If so I have to accept it and feel sorry.
Kind regards
Roland
