Thanks for this super impressive insights! I saw some of the developer streams in the past, always a well invested time, specially for organizers like us both :)
Cheating: Every rule which becomes public finds some devil persons to overcome them, so it is best to not let them be public. One day I had one member which let play the children with the same account, and boom, they got banned! So be careful if you are totally drunk and use lichess, better then to go to chess.com :)
