I have found SOME of the rules on their forums. There are plenty more but for some reason, both my accounts are permabanned from the server. Probably an IP ban.

Below are the current, upto date rules for our TTT server on Garry's Mod.

Notice: All rules are subject to change- So check this page regularly!
1. NO RDM (Random Deathmatching) - You must have proof a person is a traitor before damaging them.
2. Do not disrespect other players - Swearing is allowed however do not verbally abuse other players. This includes "umad" and anything else intended to aggrivate.
3. Do not glitch/hack/cheat - This includes glitching traps, placing objects under teleports/exits, aimbots/wallhacks etc.
4. Damaging someone with a prop = KOS.
5. Don't waste time as traitor! You will be slayed if you do so.
6. Do not use an untypeable/unpronouncable/misleading name.
7. If players complain about your voice or overuse of mic then please type instead.
8. No metagaming/ghosting. This means telling someone who the Traitors are outside of the game itself.
9. Current acting detective must declare turning off lights as Traitorous before killing for it.
10. You cannot claim rooms/areas, before overtime or after.
11. Shooting heads off Innocent corpses is considered a Traitorous act.
12. Do not randomly shoot players with dragon deagles. This is considered RDM.
13. Being the "last seen" of a dead player is not a valid reason to be killed.
14. Voice chat should only be used when necessary. You will be gagged without warning for distracting players from the game.
15. Do not ask about rank promotions or for point donations/charity. Staff applications are closed.
16. Breaking Traitor testers is TRAITOROUS.
17. You must give someone 3 warnings at least 3 seconds apart before shooting someone for following. As soon as they stop you must restart this count.
18. Do not knock down doors unless they are locked and you give reasonable warning beforehand.
19. Detectives can not order people to do anything besides Rule #20. Anyone can use Health Stations.
20.If a Detective asks for a T/Det weapon that they know you have on you, you must give it to them.
21. Looking at a "Traitor button" as it goes off is not a valid reason to be killed.
22. If you are shot then you must be absolutely sure who did it before you start shooting back.
23. Do not argue with admins. State your side of the story and let them handle it. If you do not like how a situation was handled, post it on our Steam Group.
24. Do not damage people with props while spectating.
25. Identify all corpses around you. If you miss one that was in clear view then you may be killed for it.
26. You can not kill or call someone out based on appearance.
27. Traitor baiting is not allowed, read below for more information.
28. Traitors should be given at least 30 seconds to get away after being respawned by an admin, unless they attack first.
29. If you are respawned by an admin then please do not use or share any information you have learned about the round while dead.
30. Do not change your name while you are still alive.
31. Do not make false callouts as Traitor.
32. Do not call people out or damage them unless you have actually watched them do something Traitorous or have other undeniable proof.
33. You can be killed for moving/damaging Detective equipment such as Health Stations or Testers.
34. Do not purposely disadvantage your team. Shooting a head off a teammate is bannable.
35. Do not call out Detectives.
36. Do not use the Hat Adjuster for an advantage or in poor taste.

*INVALID grounds to shoot someone:
-He/She is hurt
-He/She is aiming at you
-He/she has fired his weapon, even if he nearly hit you, UNLESS it was a weapon capable of a one shot kill or it was clearly aimed at or very close to you and is being fired continuously
-His/hers weapon matches the weapon used to kill someone
-He/She threw a grenade that has no chance of harming someone


There are many other crazy rules that are on the loading screen that aren't in their forum post. Also, there is a multitude of unspoken, made-up, and unfair rules that the 12 year old donator+/super-admins have created. Rules like if an admin is a T and is killed, they can respawn themselves, only donators and admins can be traitors, an admin can ban anyone that they don't like/anyone who kills them if they see fit. Plus, the owner is maybe 16 and the server is full of 12 year old "stoners" who only talk about "smokin mad kush and rollin gnarly blunts". I'm kinda glad I was banned from there and also glad that the Trust Issues server is 100 times better. If anyone ever feels like they don't want to play on Trust Issues anymore, do not go to the 420 TTT servers to get your traitorous fix. Or do, I'm not your mother. But if I was, I would say "I'm not mad, just disappointed".
