Since there seems to be a script kiddie going around and abusing A2C_PRINT

I've updated my DoS Attack Fix plugin to block A2C_PRINT spam. The plugin is

a Valve server plugin, and does not require metamod or Sourcemod. It can be

loaded in the middle of a game with no noticeable load time.

Both Linux and Windows binaries are included. Extract the contents of the

ZIP file to your addons directory.

 

Here is an example from the HLDS list of what the update is designed to
