[Peter Brev]

I used to play deathrun on a very popular deathrun server for HL2DM, which had ( and still has ) +jump/+use spam prevention. Limiting +jump spam could limit bunnyhopping ( not sure why you would do that, though ), or fix exploits ( none that I am aware of with +jump ). Limiting +use spam could stop people from exploiting multiple buttons rapidly for example. Use it as you will.

ConVars

sm_keybind_spam_enable [ Def 1 ] - Enable or disable plugin
sm_jump_spam_protection [ Def 1 ] - Enable or disable jump spam protection
sm_use_spam_protection [ Def 0 ] - Enable or disable use spam protection
sm_jump_threshold [ Def 100 ] - The limit of +jump commands registered in a given time ( basically, how many times you are using space bar, mwheel, etc. to perform a +jump operation ) at which it will kick the client.
sm_jump_threshold_reset [ Def 10.0 ] - How long in seconds will the threshold reset back to 0.
sm_use_threshold [ Def 20 ] - The limit of +use commands registered in a given time ( basically, how many times you are using your use key to perform a +use operation ) at which it will kick the client.
sm_use_threshold_reset [ Def 10.0 ] - How long in seconds will the threshold reset back to 0.

See plugin.usenospam.cfg ( after loading the plugin for the first time ) for configuration in cfg/sourcemod.

Admin Commands
