FYI, sometimes when I try to log on I get a message saying my IP address is banned. I'm in the Philippines so I imagine that's why. It's happened a few times since I got here (16 Sep) and when it happens it's usually for a week or two straight.
There was a IP address banned that was almost the same as the one for your above post. Your IP changes a tiny bit from post to post so maybe it'll help that I un-banned that number. Let us know if you continue to have a problem. The 162. start is the area of over 90% of our spam here.
I averaged even before you unbanned it deleting 2 to 3 spammers a night but that's because I get on in the middle of the night and I'm probably the only one that sees it.
