Since the closure of escorts.com, we have limited dedicated advertising venues here in the Panhandle. Thus, some of us resort to Backpage. As a provider, here is my take on that.
The worst thing about it is the reputation it has. Also, most of the inquiries a BP ad generates are creeps that just waste your time.
On the other hand, the best thing about BP is that first timers in the hobby may know of no other venue, and it is a chance to meet those guys. And while there are a lot of sleazy people advertising there, if a client is looking for something a little better, a classy lady will stand out. My BEST client of all time came from the old Craigslist. He was not a regular hobbyist and did not know of Eros, Eccie, P411 or any other adult site.
Of course, I screen the same way no matter where the inquiry comes from! Be safe y'all!
