How do you prevent this?

Well I was in a random TS server and I encountered this. My question is how do I prevent it?

Also for some reason my banning system is not working, I ban someone (Itested it on Myself) and tehy just come back and right wen I hit OK to ban is says error. Has anyone else had this?

It´s called "flooding"

Search for it in this forum ...

You can prevent it by a temporary password for the server.

Try for a week, an then open the server again.

Or just ban it and chances are it's using the same ip for all of them so they will be gone. If it keeps up try doing a partial subnet ban on the ip.
