It seems that Skipthegames has become the de facto replacement for Backpage. My only beef with it is that many girls are spamming it ad after ad. I understand wanting to have your ad near the top, but some of these girls have three or four in a row. Maybe it's not intentional, I guess one of the providers who advertises there would be able to chime in with what goes on behind the scenes.
Actually I have two beefs- I can't switch to "Fast Results" while on my phone, only my computer. That seems to be the most useful view.
