The internet has become the favorite place to sell women for sex, according to a CNN report. Now there is a national campaign against Craigslist and its popular “adult services” section. Police and anti- sex trafficking groups are pushing to end the “adult services” ads, arguing that underage girls are being exploited. “Craigslist is like the Wal-Mart of online sex trafficking right now in this country,” said Andrea Powell of the anti-trafficking group The Fair Fund.
