Good point. There could be a setting for the max number of SURBL callouts. If they did decide to place a large number of 'legit' URLs, they would probably have to hide them using an invisible font, obsufication or some such, so the spamee could only click on the intended URL. However, with many hidden URLs, this would give spam detection engines (SpamAssassin) more spam material to act on, and additional rules could be added to the detection set. Bayesian analysis itself would more than likely pick this up with minimal training.

I dont know if I have missed any discussion on this topic - but suppose the SPAMMER just loads up the body with random domains - that means lots of surbl calls. It seems too easy for spammers to foil this technique.
