if you go to a grocery store and get a free sample and it tastes like shit are you going to buy some of it? hell no but if it tastes great you MIGHT buy some

if you see some free porn samples that don't get your crotch stiff or your panties wet are you gonna buy anything? probably not but if you see something that you would like to see more of you are gonna check it out more

alot of the "freeloaders" are just looking for the best quality, not neccesarily eating up all the bad content out there

surfers are on your sites to check out your samples, bad samples leads to quick click backs, if they think the sites being advertised are going to contain the same type of content as your samples they are not going to buy anything from you
