Yeah, thanks for the replies guys.
Probably quite an easy (although horribly lengthy) thing to test. Would be useful to know for all those idiots (

) who spend money on links month after month (hypocritical whistle).
(If I hadn't made it clear earlier, I meant take the links down, not the site - I suspect the latter may have a less desirable effect on my sales figures).
Part Two:
Does anybody reckon that if I changed the url path of a link (though not the domain), would the link be sandboxed again? I,Brian suggests that changing any of the parameters may have this effect.
(p.s. This will be happening to one of my sites very shortly, I will let you know the results when I can interpret them - if you're interested that is.)
