While searching profiles for who signed on in the last 15 minutes, I've come across many people who have been members for 5, 10, 15+ years, but they have very few friends or likes. It's like they rarely come on the site, but they just happen to be here right now. My question is, is it possible for scammers who just joined to manipulate their registrations so that it appears they have been members for a long time? That way they fool people into thinking they are legitimate nudists.
