This suggestion is pretty straight forward, i'd imagine that some people may find it useless. But I think it can be useful and very convenient in quite a few situations.
Basically if a player has 35 hours or less, they'll have a title above their name which will indicate that they're new. The title can be something like ''Newbie'', ''Guest'' or simply ''New player''. If I came across a person with a title like that, I would personally approach the player and see if they needed help, instead of checking people's stats individually which is something that nobody does. Or if a new player violates a rule, instead of reporting them straight away you can just give the player a warning and tell them that it's against the rules. That would save everyone time.
You'll probably say that they can just read the server information and use support. CIT is a heavily modded server which can be very complicated for next players. Believe me, having someone helping you out in person is a lot better than constantly spamming support and main and then ending up getting muted.
