Basic neutral listing sites with links to resources like Backpage outwardly appeared probably are; to the extent that the allegations that the operators actively collaborated with and knowingly worked to conceal trafficking of minors, Backpage itself may not have been.

While there is clearly a crusade against the former (as the aerlier attacks on CLs erotic/adult services listings made clear), and that's probably why Backpage got lots of attention in the first place, it's not clear that the reality of Backpage matched the surface appearance or the reality of the earlier targets.
