I've seen this a few times and still can't figure out why it's done except maybe to increase chances of getting listed at the site that's got the recip next to the 'big guys'. It's fake recips so avoid that shit like the plague
On the stat end of things as far as click tracking goes, not all webhosts offer referer logging in your stats, let alone aggregate it out by directory/page, the only way you can reliably do that is have some JS tracking going on but a lot of linklists will not accept any sites/galleries that have JS on them at all (although I think the rule first originated to prevent people from pulling dumb JS tricks).
