As SuperWaffle said
He's doing something to the actual server instead of the client,
I don't belive he's connecting to the Client, but connecting directly to the server.
What you could do,
is only allow connections from registered accounts
as in
no one but a certain IP can connect to the VPS (or where ever it's hosted)
that way, the hacker/crasher couldn't actually crash the server
I don't know if this is actually possible, but it may be an idea
