My guesses are that the public sign just made Admins getting spammed for every little sh*t and it'd only take Admins longer.

I will never understand why noob with 2000afk hours do get Admin when there so many more active experienced players that could get the job done, might as well just hire a few PKers / Sparrers that only get the option to warn players, I don't see how this could effect any player, there enough mature people that'd do this job better than most in the GP Team
