Forlix FloodCheck

This SourceMod addon, (made for CS:S, but might work with other mods) provides chat and command flood protection, especially useful for ma_timeleft/nextmap/etc. spammers, as it will kick those instantly. Chat- and radio-flooders will get the message "No spam!" and be blocked for a certain amount of time. Players flooding the server using a flooding-script such as with ma_timeleft, will be kicked instantly, and temporarily banned on the second flooding attempt. The plugin integrates very smoothly with the game, as it also takes care of chat and radio deadtimes (0.75 and 1.5 seconds respectively) that are imposed by the engine itself.
For example: If a player executes a radio command twice within 1.5 seconds, it will only be counted once towards flooding, as the second command would be blocked by the game anyway. The same is true for chat messages, only with an interval half as long. The plugin exposes the native "IsClientFlooding" which can be used by other plugins to ignore chat commands while a player is flooding.

The plugin also blocks alot of dangerous console commands, some of which are capable of crashing the server in certain situations. It prevents the server crashes caused by people sending many incorrect rcon passwords, as well as people using certain programs to make the server crash when they connect. Control characters, such as line breaks, CS:S color codes, are taken care of as well. Players having such characters in their name will not be allowed to connect, and chat messages containing these characters will be blocked.
