A lot is wrong with it when it’s mixed with couchsurfing. It may not be obvious to you, but it really harms the uptake of the hospex for women in particular. See Should Couchers.org make it clear that the platform is not for dating? for a very clear picture of why we came to that decision.
Also, as a general response to your topic, the women on our volunteers team, women’s working group, and in our community want a flagging system, and the benefits of it evidently outnumber the drawbacks for us. Specifically, it allows people to avoid aggressive/dangerous confrontation and also helps victims remain anonymous if they so choose. Not sure if you read through the shared bed thread, but our community was largely against the idea of it.
We appreciate your ideas and I’m happy to see your post though! Thanks for joining the forums
