Ah, so a subdomain. I can see why some admins might do that...

Perhaps inconvenient in the short term, but it seems you could remedy 
that problem long term for about $10/year by registering your own domain.

I agree that it is short sighted for admins to block all subdomains from 
dynamic DNS providers, but these days a lot of babies get thrown out 
with the spam bathwater.
