My roommate, before he passed away, ran a website for escorts safety. It was a subscription site, broken up by location, where escorts could post information about clients who either ripped them off, no showed, got violent, etc. That way escorts could go check and see if their client had a history before any meeting.
He’d get angry letters and emails from men who were mentioned on the site demanding the info be taken down. The site was indexed by Google. He would take the info down if there was some sort of proof that the incident didn’t happen or that it was a fake report. Otherwise, the info stayed up. He got sued a few times, always won thanks to the CDA. He also worked with the FBI and local police from time to time. A few guys ended up in jail, one of the guys he talked to the FBI about ended up on national news when he was arrested.
Before he died he was working on a plan to expand to dating websites like Match.
There was some abuse of the site. He would remove posts if they were proven to be false but that is a hard thing to do. IIRC, occasionally people would get court orders to have him provide info on the user who posted so that they could sue that user. I think once he had to remove some posts do to a lawsuit against the poster.
It seemed to work pretty well. However a) it was subscription b) had a small set of users and c) he was working towards going fully private and removing indexing so info wouldn’t show up in google/bing/etc searches.
The reason to take it private? Remove the incentive for false reports.
My roommate and I had quite a few conversations about the usefulness of the site vs. the potential for abuse. For the site he ran, the number of false reports was pretty small. But it also had a small, specialized user base that, due to the nature of their work, was a prime target for being attacked/robbed/whatever. The short answer was we never figured out a good answer to the abuse angle for large scale implementations.
He passed away and now I own the domain. No idea what to do with it. Keeping the site running was too time intensive and it required a full on rebuild. I may, if I can find the time, rebuild it and make it more automated. It made decent money, just took a lot of effort.
