Next time some one complains about the rules, tell them with admin chat to come and complain here on the forums (where we will just laugh our butts off) instead of in-game. If they won't stop, silence them and let them have a few minutes to calm down. If all else fails and they simply hate our rules and want the whole world to know, give them a kick.
As for your last question, here is the list of server-specific rules (minus Jail):
All Servers:
Players must attempt the objective. CT's defuse a bomb, T's plant a bomb. W/W/K
Re-buying of grenades is prohibited. W/K
On bomb maps (Highschool/Dust 2), wait 20 seconds before dropping the bomb from an AFK T.
Admin less on servers with low population, extra warning is okay.
Dust 2:
Spawn Camping - Out to Long A or B tunnels or Catwalk by 1:30, T-Spawn Clear. You may double back through spawn but no camping. W/K
Highschool:
Spawn Camping - T must be through T stairs, parking lot tunnel, and side yard by 1:30. W/K
Office:
Spawn Camping - CT must be out of garage, side rooms, yards, and front office by 1:30.
CT must make an attempt to rescue hostages, W/W/K
Italy
CT must be out of spawn by 2:15
CT must make an attempt to rescue hostages, W/W/K
Finally, the admin trainers and the G, O, and Admin Q&A forums are the places and people to go to if you need to more specific rules for other issues. Add any AT to your Steam Friends list. We want to help.
Hope this helps.
