troll is exploiting Battlefield1942 software

I've been playing battlefield 1942 ever since it came out and still am having a good time on the game I even bought copies for others to get on.

I now particular play one server but we have this troll that keeps coming to the server and crashing the server, were having to put a password on the server to keep the troll out and it's causing us players.

I mean this troll has been sending malicious private messages to the admins Swearing it going to keep Crashing the server and, I understand the troll crash other servers too.

This has been going on for about 3 years going on four now.

Is there a way that we can be helped to fix this exploit in the software?

P.S.: I'll be totally grateful if you guys put Battlefield 1942 back on the shelves or steam or origin and I deftly will recommend people buy that game.
