To be fair...
I have been on the server many times with Columbia.
I have also gone to spec a number of times (while Columbia is in spec) to ban cheaters. But I have also tried giving advice about players on the server and general tips for admin.
Along with not banning, the main problem i feel is use of tsay. There have been a number of occasions where i have been playing on the server for some time and it is ok (no hax and good play). Players are playing, you get the odd camper but that is CS. But then columbia joins and sits in spec and then spams tsay for campers to move which is met with complaints from players. I have said a number of times in admin chat to "let them play", which i don't think he has seen.
I am not going to judge, as he is a new admin, and with that comes learning. Whether that is good for the server or not is another issue....
I genuinely don't think he sees cheaters on server yet and has not "found his feet".
