So, this has been asked quite a few times on here. But I'll explain it again anyway,
Camping gun room means you are in the gun room well past the time of getting ready for the round. E.g if cells are open, and you go back to gun room, and you loiter / change weapon and spend unnecessary time in there, then you are classed as gunroom camping.
Vent camping is where you either camp the entrance / exit to the vents, or keep a vent within your fov waiting for Ts to enter / exit it. For example, sitting in the medic on blackops waiting for Ts to exit the vent. This also means if you are away from Ts and in sight / in the vicinity of the vent, you are classed as vent camping. Long story short, if a T exits the vent and has no reason to expect you to be there (if the vent is closed) you are vent camping.
These rules are in place to give Ts are more fair and reasonable chance at rebelling each round.
To answer your last question, to stop Ts from going to gunroom would be to control them. This means making sure they have no opportunity to enter a vent. A good warden / a good CT team can control a round.
ALSO, if you clear vents (this means going in AFTER a T and killing all Ts in the vent) and spending extra time in the vent / the exit, you are camping. As soon as you clear vents, go back to watching the non-rebelling Ts or hunting rebellers that have exited the vent.
You should not be waiting to catch Ts at the end of a vent or gunroom, that's pretty much it.
ALSOx2: Being an admin in-game can get quite hectic. On a full or chaotic server they have to be constantly sorting out problems / issues, so arguing with players, especially newer players is time consuming and shouldn't be happening over in-game admin chat. Asking questions is fine, but arguing or continuing to ask questions over and over can hinder an admins ability to do their job.
