We frequently get complaints from service providers about other ads in their cities and they ask for an ad removal. Unless an ad violates our posting guidelines, we do not remove ads.
Different people are looking for different things. Some like the asian parlors, others like having sessions in shady motels, and some are looking for a CMT with candles and aromatherapy. We're proud to say we have advertisers to meet most any interest in the massage/body rub world, and we plan on keeping it that way.
The main reason for the favorite & hide buttons is to allow the users to decide exactly what ads they want to see and which ones they don't in order to tailor their experience.
