This applies to all servers not just the Spawnpoint servers.
When you think someone is using hacks, but it's not completely obvious, follow these steps for best results:
1) Don't say anything over text or voice chat. Cussing or accusing them is pointless. If they aren't actually hacking, you're just harassing them. If they are hacking, then you are going to make them toggle their hacks off and do things to make it look like they're not hacking.
2) Leave the server.
3) Change your nickname to something inconspicuous.
4) Rejoin the server and begin spectating the suspect.
5) Begin recording a demo by opening your console and typing
record demoname where
demoname is the name of the suspect.
6) When applicable, type
sb_status and
status in the console to have their identity recorded in the demo.
7) Watch for as many rounds as necessary. Type
stop in the console when finished.
8) To add them to the Spawnpoint Global Ban List, email the .DEM file (located in your cstrike folder) to
hacker@phxx.net.
Keep in mind that if it's not an obvious hack, the player could just be very good at the game even if you believe they are hacking. For this reason, harassment of the suspect is not a good idea unless you want to potentially be a jerk.
