Who runs the Lichess account on lichess?

Hello! I received a message from Lichess account, accusing me of a possible violation. However, I can't respond to the message or ask any related question. Is this normal? Only one side has the right to send its message. Why?

Lichess mods use the @lichess account

Meaning whatever "Lichess mods" send, one should accept it?

"Game completion rate: 83%" Probably there was a good reason for it too

In case they sent you a warning:
lichess.org/appeal#help-clean-warning

Don’t discuss, just do it.

Thank you @sheckley666
