Spam that is just a link

I'm increasingly seeing spam like:

"Cut your debt: http://some.link.com/link rkljelrkjhvljher90135h3434"

There are usually more random strings or random words and meaningless
sentences along with it.  I think in some cases dcc misses these.

Perhaps there should be a new checksum for all URLs appearing in a
message?  That might catch these along with spams that are nothing
but HTML <img ...> tags that refer to off-site servers.
