	I call this spamchaff - useless links thrown in just to throw off 
spam fighters like ourselves.
	Some of those hyperlinks are simply [a href="...."][/a] with no 
target in the middle.  I specifically check for those "empty links" before 
even starting the normal process of extracting urls.  Another common one 
is 3 link pairs, each surrounding a single character of punctuation.

	Agreed, and this is why I've spent a _lot_ of time working on the 
scripts that extract URL's so that I can see these and they won't hit 
the list at all.  It's also why I'm finding I have less and less patience 
with other people's scripts as these slip into their submissions.
