Not sure if this is a new type of spam or not:

This example I just received had many real or joe job URIs with no text in the anchor like:
<a href=3D"http://www.elysian-MUNGED.com%22%3E</a>
Perhaps it's trying to run out some counters, but the real target domain is visible as the last "removal" URI:
<a href=3D"http://= www.ozone.fitch7826drug-MUNGED.us/d.ddd">here.</a>
Name: fitch7826drug.us Address: 61.250.93.214
Where this IP is in sbl.spamhaus.org of course.
The "ordering" link just before it was broken (no dot, at least in my MUA, The Bat!):
<a href=3D"http://fitch7826drug= us/b94">Click
Interestingly SpamCop did parse the message correctly in terms of ignoring the blank anchors and finding only the clickable ones.
That said, if urirhsbl or SpamCopURI limit the number of URIs checked, these could sneak through. A useful behavior might be to ignore any non-clickable anchors, if we're not already doing that.
