If I was on the server:
When XXX first states AAA is hacking/cheating, ask XXX why he thinks AAA is cheating/hacking. If the reason given seems legitimate, I would check HLstats and AAA's steam account for any suspicious signs (low play time, High k:d etc...) , then switch to spectator and observe for any signs of hacking- Locking on to players, even cloaked spies (aimbot); Shooting/being able to see through walls (wallhack); perfect backstabbing- not seeing the knife come up before a backstab every time (autobackstab/automelee); Always/ mainly having crits (crithack); Increased speed (speedhack). Hacks such as esp are harde to detect, but if player AAA is able to kill EVERY spy that is about to backstab him then it will raise suspicion- and will consult other admins before action is taken on AAA.
If action is taken, I would record a demo before banning with the command: /sm_ban "#STEAM_0:0:0A0A0A0" 0 "*Hackname*"
If I was responding to a report:
Whilst connecting to the server, Check AAA's steam profile and HLstats as above. Then switch to spectate and determine whether there are any hacks being used- as above.
If AAA is hacking/cheating, then I would record a demo and ban with the command: /sm_ban "#STEAM_0:0:0A0A0A0" 0 "*Hackname*"
If AAA isn't hacking:
After determining that AAA is not hacking, I would send a private message to XXX using: /sm_psay "XXX" "AAA is not hacking, so please do not start another vote or report- as it will be classed as abuse"
I would then stay on the server for 10 minutes to make sure another vote or report is not started, then go back to 2fort :3
(If XXX starts another vote after this warning, I would ban them for the appropriate legnth of time.)
