Few websites get the chance to choose which advert they get sent. They usualy employ a third party agency to serve the advertising and collect the fees. Sometimes the agency picks appropriate ads, sometimes not. I have seen Cartier watches promoted to an unemployed readership, fried chicken after a vegetarian feature, and suchlike mistakes. One day there is an ad to meet sexy men here, other days it is to chat to sexy girls. The Gay Heaven staff do not, I assume, have any say on which ad happens to turn up on any one day.
