Oh yeah, with a few of the just looking for sex sites, it seems like you register, get a few messages from "Gold" members, and if you choose to pay for the upgraded membership, the people that were sending messages disappear. I've heard this about Adult Friend Finder, but I know one girl that had a gold membership and met a few people. These sites have much more men than women, so maybe creating a profile for your wife, and blocking out the inevitable storm of male responses would actually be effective.
