The suggestion is that the Jailbreak server has a requirement for you to have played on the server for a certain amount of time before you can join CT. This means that if you are below the minimum play-time requirement, you cannot join CT. In other words, this would be blocked by the server, with a message like "you must have at least X minutes as an alive T on the server in order to play as CT". This could reduce or remove a number of issues. 90% of new players that join CT break rules and have to be swapped or CTBanned. The suggestion could solve this problem. We already have the rule "If you don't know the game or are new, you must join T!". This rule supports the suggestion.
