I can't see the image you provided but I'm assuming it was something in the replays.
Regarding the name he called you and talking about the other person (Jasmine) - I can't mute someone for those, they're minor and honestly you know they're untrue.
Considering I can't give him an actual warning or mute, the user can be verbally warned, meaning if he's reported for this again or acts like this again (especially towards staff members), he will be warned or muted.

Thanks for the report.
