The majority of spammers/trolls/attackers come at about the time I'm creating this thread, about 11:40pm (-8 PST). The reason for this is that there is no pst night moderator, I never see one in the online list.
Moderator's are volunteers right? Though I don't know if the problem is big enough for this site to recruit, if it is has anyone got any suggestions? A trusted users in the PST timezone? My vote would be Sonart, but I forget where he is.
Remember, not someone who shares your views, but someone who'd respect them and promote a healthy environment for the site.
