I don't know how this should work... Of course, there are a lot of people who have a continence problem, but they perceive this as a flaw and would hardly use the idea as advertising for dating. The only ones who might want that are DL's and possibly a few AB's. However, everyone outside of this scene can hardly do anything with it. Within the scene there are very few women and they are then usually more AB oriented than DL. As a result, such a project would be doomed to failure, because even if you built such a platform, it would be overcrowded by (male) ABDL within a very short time and all women would turn away with gray. Those who belong to the scene will hardly have a problem finding someone on the well-known platforms...
