We instituted a policy where the first post of every new member must be approved. While this is somewhat of a convenience to legitimate new members, it also allows the mod team to pick out the SPAM and ban new member spammers before you ever see them.
I thought I'd share with you what we see on a daily basis. This is a screen capture of the SPAM threads we move (the forum isn't visible to anyone but moderators). If you ever what your mod team does, here is one example. nearly all of these threads were identified as SPAM and moved before you saw them! Further, the user accounts were banned permanently.
Just one example of your mod team at work, behind the scenes.
We really need to give our mods a hand. They do alot that we never see so we all have a nice forum minus all the BS on the net defacing it. I know a little about how/what they do but my forums dont compare to this one in membership.
