My guest posts still haven't come through Lol
And they probably won't. 90% of the Guest posts there are from regulars like Chum Li or Fashionista. They'll enable Guest posting for themselves in the control panel, post their BS as Guest, and then close Guest posting again.
They actively monitor IP addresses of Guests that are browsing the board (not even posting, just browsing), and ban IP addresses that they don't recognize. To do this is an extremely time consuming process. For instance, I have hundreds of proxy IP addresses that I can cycle through, and they'll manually ban them because they don't recognize them as an IP address from a regular. There is no way for them to tell who is behind any given proxy, but they'll ban that address anyhow.
It's actually a sign of mental illness for them to do that, seeing as how time consuming it is for them, but they'll sit there in the background and do just that. I'll do just that just to toy with them every now and then. It drives them crazy.
They may as well just close down the Guest board, since Guests can't actually post there. They just keep it open so they can abuse the mod panel.
