Plutonium

I just started playing Plutonium and joined the main big Waw Server "NamelessNoobs" or w.e its called. Played all day, didn't have any problems. go to play later at night after I took a break and I'm banned from the server? Anyone help me out on how to contact the admin of it to get unbanned? I wasn't given a reason tbh so I'm a bit confused. I have recorded gameplay so idk what it could have been. Highly doubt they thought I was hacking or anything along those lines. I hit a few sniping clips tho
