The chances of you randomly connecting to even a VPN IP as the same person banned on our server is slim to absolutely zero, it can happen but it did not in this case. In this situation with the proof provided by randy it seems that you were banned for DDOS Threats on your main account and have tried to return to the server later on, under different hardware to possibly evade a ban.
Adding onto this, there’s viable proof that you were borrowing this account from a person who was banned for DDOS Threats, which makes it seem as if you were the guy just trying to evade.
If this was not you, I suggest using your own GMod, since you’re “not the guy we banned” you should’ve made sure the guy wasn’t banned, if he let you use it willingly like that, I don’t think he’s really a good friend man.
-1, I just don’t think any of what you said is true, this is like a Dream Speedrun with how little of a chance any of this could’ve actually occurred.
