Danny-
The problem is that I do not want to unblock Michael, who, though I have not been following it in great detail, it appears really should be blocked.
Michael is blocked under his latest pseudonym, NO-FX -- unblocking your IP address will not change this (we can block both by IP and by nickname). Besides, since the IP address is dynamic, it is unlikely that whatever vandal originally used it will get it again soon.
Regards,
Erik
