Corruption is everywhere. Because Craiglist removed it's escort section, that made BackPage the primary source for these escorts. If BackPage removes its escort section, another website will appear. Don't these people get it? Prostitution is the oldest profession, there is no way to avoid it.
Underage proposition is not good, and the pimps should be blame for it. Some men such as myself use BackPage for legitimate girls, and avoid girls looking like 15 or so. Seriously, I do. So, what ever the case may be, there will always be another internet site.
