Warpath has been very quiet lately, apart from the occasional person with an inappropriate name, who is quickly dealt with by the admins. At times, half or more of the players there are eGO members, and with the amount of mic chatter going on among us, there isn't a whole lot of opportunity for people to interrupt and start causing trouble.
2Fort also seems to have a large number of eGOs, and I know some of the regulars there are admins.
Dustbowl can be a mixed bag. At times, it can be pretty troublesome, especially after the admins leave. I remember times where people would explicitly ask if there were admins around, and others would reply that they didn't think there was anyone with admin powers around. I also tend to see multiple members from a clan show up at Dustbowl, more so than some of the other servers for some reason, and that can mean trouble because they tend to get bold in numbers.
I rarely play the other servers, but one of the only times I was on Gravelpit, I remember Bubbles getting a bit of grief after she asked someone to stop cursing.
