It's too bad the pimps and prostitutes ruined casual encounters. Craigslist had to remove it because some people were using it for prostitution. It was a safe place to arrange experiences that you would never have had otherwise.

It's also too bad our society shares in the collective delusion that sex work can be prevented. It not only makes sex work far more dangerous, but it tramples on these exact kinds of novel spaces for sex/intimacy.
