Many immediately started posting in the dating section, which leads me to believe that they were using that section as well in many cases already. Possibly to attract different clientele, possibly because it would be a cheaper if not free place to post ads.
Like when CL was shut down, day by day escorts found another way to advertise and stay busy. i do hope that those clients and escorts together stop relying on just one single ad location, and branch out a bit more onto other sites. it's the only way to lessen the immediate impact of this kind of action.
