4* for not making everyone pay and the limited number of people I can communicate with inside the app. I used roommates.com to find a roommate to move into my place in 2005 and again after I moved in 2007 (14 years, then he moved out and got married). I'm looking again and pickings are a little slim since I am looking for only a mature/no drama male. I am a woman and prefer not to tell someone my name and where I live until my fiance and I have had a chance to meet and chat with them, so Facebook is not an option. So, I'm resigned to paying $15 a month and staying on top of the new listings so I can contact potential renters before they get jaded by the scammers. It isn't perfect, but I don't blame the site for that and they do have a report button and you can block people from messaging you. If they can't read my message and aren't willing to pay $15 to find a place to live, they probably aren't going to pay $45 for a background/credit check or pay their rent either so I won't contact them off-site. As far as paying, do you work for free? I'd love to find a roommate site that does a background/credit check as part of the sign-up process, would get rid of the scammers and some of the non-paying and violent/dishonest roommates and well worth the price.
