What to do if you detect a hacker on the TF2F servers

Step 1:  Get corroboration.  That is, ask other players (voicechat or teamchat if the suspect is on the other team, steam messages or vent if otherwise.) if they think the suspect is hacking too.  Going into spectate and watching them for a while helps.  If it looks like a hacker, and you've got corroboration, go to step two.
Step 2:  Find an admin. Admins include Lancer, Durban, and teamchuckles!.  There are others, but those are the ones I know have the rcon password.  In the process of step 1, you may already have found one.  Let the admin know about the suspected hacker.  The hacker will be kicked and/or banned.  If you cannot contact an admin, go to step three.

Step 3:  Open the console and enter the following commands in succession; "status" and "condump".  "Status" will identify all the players on the server by their in-game names and their steam IDs.  "Condump" dumps the entire console into a text file in "C:\Program Files\Steam\steamapps\(playername)\team fortress 2\tf", and names it "condumpXXX.txt".  If it was your first condump, it will be titled "condump000.txt".  If it was your second, then the name will be "condump001.txt", third is "condump002.txt", etc.  Once you have done that, go to step four.

Step 4:  Record a demo.  This is done with the console command "record (demoname)".  Stop recording with the command "stop".  Replace (demoname) with what you want the demo to be called.  Parentheses not required.  Going into spectate and recording the offender will help greatly.  When you have finished recording, upload the demo and condump to an appropriate website and submit a ban request at this location.  An admin will review your request, as well as the source material provided, and determine if a ban is an appropriate action.

Thanks for posting that, Scorch.  That will, no doubt, be useful to many of us regulars looking for continued clean, cheat-free games on the T2F2 servers.

I thought I saw someone using a speed hack the other night on our servers. I made the mistake of mentioning that I was going into spectate mode because I thought someone might be doing something funny. After that, the guy switched classes and I never saw anything out of the ordinary. I don't remember his nickname and I don't recall seeing him before or since. I'll keep all this in mind if I see anything abnormal again.

Cheers, I imagine the fellow who was kind enough to wedge himself inside the spawn door on well repeatedly would have qualified for this.

Sticky worthy, thank you.

Updated with instructions on how to record demos.

whats a wallhack?

^ When you can see/shoot through walls.

Very good post. Iv'e spec'ed a couple supposed hackers and have a couple tips:
1. Don't say anything about some guy hacking, just say somthing like" AFK for a sec" or the like and go into spectate.
2. First Person Mode (Spacebar) is alot more helpful than just watching from Third since you get to actually see how hes getting his shots.
3. Aimbotting is easy to spot since he will obviously be a sniper, and always seem to get impossible head shots, will take very little time to aim, and every now and then the crosshair can get stuck on things
4. Wallhacking is very hard to catch since if they are good they wont do the obvious thing of following people that they "cant" see and always seeming to be prepared for someone to show up, very hard to distinguish from just a really good player.
5.Even though its not necessarily cheating, alot of times when a person uses alot of scripts when they play can also be using other methods to better there score, so looking for people using scripts is a good start, and alot of time you can tell if someone is using scripts by watching them switch weapons. If they switch weapons a couple times when they first spawn, probably using scripts. also if they switch weapons right firing there is a good possibilityof them using scripts...

Hopefully someone finds these helpful...

best thing i ever saw was an aimbotting pyro he just failed and when he started getting upset because mainly everyone was dominating him he cryed why wont my hacks work which resultedin him being kicked lol
