Well, i'll start off by saying how awesome the Gmod server is, The TTT mod is fun, and the server is almost always full at night. Our server becoming so popular in such a short time was really great, it's fairing by far beter than our short lived venture into TF2 (RIP TF2 Server, RIP).
Now then, onto my concern. This evening i went onto the Gmod server, planning to spend some time enjoying the fun of killing innocent terrorists and what not. All was well for a bit, until a hacker came on. This hacker had Aimbot's and speed hacks. The hacker proceeded to make the server a miserable place for us, killing everyone, regardless of wether they where innocent or traitor. Annoyed, i decided to get an admin to come over and deal with this bastard.
I then began a long quest of actually finding an admin who had powers on the server, i spent over an hour asking different people if they had admin powers on TTT, and asking those admins who lacked Admin powers to inquire on Vent for anyone who did have Gmod server powers. During this time, more hackers came, causing grief for us players, and slowly causes people to leave.
It took probably close to, if not more than 2 hours to finally get someone with admin powers onto the server and deal with 2 of the 3 hackers. 2 Hours. Most admins i talked to said they didnt have Admin powers on the Gmod server, and i know none of us apprentices have powers on it either.
I personally feel that if we do not have more people with admin powers on the Gmod server to deal with hackers, griefers, etc, then the server may eventually loose it's popularity due to hackers coming on, and no Admins there to deal with it. 2 Hours, in my opinion, is way too long of a response time to hackers on the server. If more people had powers (Like all of our SG admins), I'm certain that the problem would have been dealt with in 10-15 minutes tops, depending on if there was an admin in the server at the time or not.
