"You lost to someone who violated the Lichess terms of service".

Good afternoon sirs.
I received a message from you guys yesterday, saying the following: "You lost to someone who violated the Lichess terms of service. Refund: 5 Blitz rating points." Can you please tell me who violated? because I need to punish the team, according to our internal regulations. Thanks. My username: carvaflu
