Our directory is made up of links to sites that contain travel pictures. Each of our pages links to a different country or region.
Some travel photographers set up their sites so that each of the countries they cover is on a different page, and they encourage us to link to each of their country pages from our corresponding country page, a natural arrangement.
One photographer, whose site I am studying for possible placement in our directory, has about 40 pages we could use throughout our directory. The problem? What if this person decides to do us a favor and place links to each of our pages from the corresponding pages we've linked to from his site? I wouln't feel comfortable with that at all.
I've thought about mentioning to the photographer the hazards of him linking back to all of our pages like that, to discourage any ideas he might get. But what would stop him at any time in the future, maybe if he got angry at the world or something - what would stop him from posting links to all of our pages, and then, before I had a chance to remove all his links, have googlebot come around, chew up both of our sites and then spit out two PRO's?
In the above scenario, I would be putting power in his hands to possibly adversely affect our site, which I don't think I can bring myself to do. The situation is unfortunate, because he has some great pictures and would love the exposure, but I'm left wondering just how many of his pages I can safely use.
