Hello,
After reviewing this situation, I do not consider this either abuse of power, or harassment.
We do not moderate chat, this includes chat involving a moderator. If you choose to keep chat unmuted, you agree to accept all consequences of what happens in chat. If you do not want to interact with people on Omega, you have the ability to block them on discord, which blocks all communication through Omega as well.
Merry Christmas
Catto
