This is along the same lines as a suggestion I made a few months
ago, to come up with a standardized format for checking partial
or complete URLs against a blocklist.  That would definitely 
allow targeting spammers who abuse free or cheap web hosting 
sites and URLs to redirect to their real sites.

Personally, I'd prefer a protocol that used the actual URL,
perhaps base64-encoded, to this, for a couple of reasons. First,
this format only works for sites that use a URL structure similar
to Geocities -- they don't all.  Second (and IMHO more important),
there are a whole lot of phish sites and hacked/trojaned sites 
with downloadable viruses or trojans that could be targeted
precisely, without false positives, if you had a format that
accomodated complete or nearly complete URLs of any format.

But I like your idea. :)
