Add search feature filtering, and add a feature to hide "pay me" profiles.
For paying members I would recommend adding a feature to the search that applies a "not" criteria for the search, such as "Not a Feedee", "Not a Woman", or "Not Married". I think that wouldn't be too hard to implement and would be very useful for searches. Of course it would have to work with searching for things too, like: searching for women who are feedees, but not identifying as a BBW.
Another filter for paying members that would be amazing at saving time is to hide profiles who have a primary interest in making money through video/skype-shows/gifts. There are so many profiles on here built around wanting to get money for food or money in general. Posts are limited for advertisements in the current terms but it would be nice for profiles to be moderated by somebody who looks if the profile is built around solicitation to mark it as a profile that can be hidden.
