Re: further proof
Serious question: Have you bothered to try forming a balanced opinion, by say, reading something else than one-sided propaganda from people on a personal crusade against Backpage in particular and Internet services in general?
Some quotes to shine a _slightly_ different light on this:
'In total the complaint mentions nine ads, for which Backpage received $79.60. It does not allege that Ferrer, Lacey, or Larkin knew the ad-posters were discreetly offering sex for cash, knew the ad posters personally at all, had ever seen the ads in question, or had any direct knowledge of these ads.'
'Ferrer and his co-defendants, Michael Lacey and James Larkin, were booked for pimping, pimping a minor, attempted pimping of a minor, and conspiracy, based on the state's contention that they know some of the tens of millions of user-generated posts on Backpage.com are veiled ads for prostitution, sometimes involving teenagers.
As evidence of this, the state pointed out that Backpage blocks ads explicitly offering prostitution, states clearly that ads in the "adult" section can only be posted by adults, and promptly removes posts that are reported to advertise sex or underage women. In the topsy-turvy logic of the criminal complaint, the fact that Backpage policies are designed to prevent commercial-sex advertising and the prostitution of minors shows that execs actually condone these things, because said policies encourage posters of illicit sex ads to conceal their true intentions.'
'The former Backpage owners suggested that California's AG knows she won't prevail here but doesn't care because conviction isn't the point. Their arrest in early October generated massive publicity for Harris just before the election, almost universally portraying her actions in a positive light.'
