Why are there links to breeders on this site?

This is a question we get often. We do have the ability to "filter" out specific advertisers one by one. We debated over weather or not to filter out breeder advertisers and decided against it for a number of reasons. Our biggest reason is that we think it is a fitting irony that breeders are partly responsible for paying the cost of maintaining this site. We should also state that the breeders who advertise through yahoo can also "filter" out our website address, so that their ads do not show up on our site if they don't want them to.
