Hello zeus,
The hostile and aggressive behavior when it comes to role-play from Gmod has been taken note of before your report abuse. This is not how we expect staff or player to behave like, this along with his previous report abuse will be discussed in the meeting.
However, I would like to point on Gmod isn't alone on this. You guys constantly argue back with one another about raiding and s hit in group chat, it's getting old. Are these messages by him acceptable? No, but you need to consider you guys have constantly disrespected him and others the same way in the past. I suggest you guys work out your differences as I'm sure it would solve your guys' problems.
