Got snared by the system again two or so nights ago.
Though it has been no trouble other than that one time, so that's good. Is my IP changing around alot? Just for information's sake I haven't logged in on any other computer or used a different connection, but am using a USB 'Dongle' that connects to a wireless network.
You have to be getting an IP address in that blocked range when this comes up. Unfortunately, your ISP must be using part of an address space that has been the source of a lot of spam posting. I narrowed the block down as much as possible. It sounds like the problem might be that the wireless network you are using is also the source of a lot of spam accounts.
