I've never noticed (and definitely haven't clicked on) a sig spam link. I've hovered my cursor over sigs before and saw that some had links mostly for Opera, FF, MBAM, etc., and sometimes what looked like maybe personal homepages or Facebook, blah blah. What would a sig spam look like, and usually what do most of them link to? I'm not asking for any links, just a knowledge of what their typical scenario is. I'm assuming you can't tell they're spam till it's too late since you've already clicked the link.

Thank you Hazelnut, mighty Killer Of Nasty Spam Thingies!
