Request for scripters: Death/ESC-Ban

[SNAFU]

May I ask any talented c# expert to give me a hint how to install a kind of "death ban" script of online-players for

-leaving their plane via ESC without beeing on safely on the ground
-after X number of deaths

to have a ban for Y minutes.

To draft our server-concept:
We run an dedicated online server and our approach is orientated on historically circumstances and based on daily reports of missions during July 1940. Every ingame hour one mission is launched to simulate certain events of these days as far as possible with the given tools. The nature of these missions demand teamplay and organization, the player will have little chance flying alone or in small numbers and should stick to the tasks given. 95% of the online players just jump into a plane and go straight the shortest way to where they expect to find the fast action, that`s utterly ok (I myself do this also, when I am in the mood), but to have some diversity in servers, we choosed to keep this kind of gameplay out of our server as far as possible. (There are other and better servers for the fast fun&action).
That`s why I am looking for a tool to "punish" players, who just press ESC to choose another and give killed pilots a few minutes to think about what they did wrong.

Any help would be greatly appreciated.
