on our server, we usually have a friend or two , who comes with rhinos and kepy them trampled and on the ground, while we do the knoking. in pve helps to have good friends to go and help against the idiots who comes and populate servers.
in our server we had a guy that did a dick move on us and stole a t4 beearer, only incident we ever had, we grounded him in his base for more than a day, the whole server went after him, got caged in his place (in jail) until next day, it was so bad for him, that he ended up apologizing and now he has become even friendly with others., doing bad things to people over a PVE server,. (if the server is good) carry consequences for the offenders, well at least our server seems to work really good with the in house rules set by the three major(larger) clans , in our server no one shows up in someone else surges unless invited, but people are allowed to watch from a distance. xd
