Gary, thank you for making an inquiry and sharing it with us. After I failed to sign up as Kabinopus, I signed up with my real name, that's why there's a confusion.

I have access to the forum to read and write right now, so I consider the issue to be resolved, although I don't really use it much.

The arguments of the administration may be reasonable or not; that's their call. To me it seems a bit odd, because I have signed up on dozens of forums during my life, sometimes just to post one message, and never I had to deal with this sort of protection.
