We need amx_showcvar
and
"listing keys" used in the game - this plugin i think exist too, admin can use some amx_ command for show what player used in round, admin can see listing all keys during round... i think it was somethig like amx_showkey "Silverquick" or something like this...
next, there is need to create enter configuration... example : sv_cheats 0 , ...aim 0 etc.
- if player will have ...cheates or aim setted to "1" , he can not enter the server....
