My email address has been blocked from the Technet forum. Why? Help?

I was participating in the technet forum (as well as answers) as a replier.  Then my email address was blocked.  Kinda embarrassing as a MVP ... <sigh>

I don't know why and I have not been able to get any help to get it unblocked.

I was directed to this forum in this trouble shooter:

http://social.technet.microsoft.com/wiki/contents/articles/13976.how-to-troubleshoot-microsoft-account-issues.aspx

I can log in to the technet forum from the same computer using an alternate email address/id, but I don't want to do that.

Any suggestions on who to contact?
