I enjoy Itch.io for the adult content, its the first time in my life I have ever felt safe enough to actually consider downloading something of this genre and so far it has been safe and fun!
I rate games I play not because I think I am special or because I think anyone cares. I rate them to hopefully provide some clear feedback to the people that work hard on their projects and also for people like me that have bad internet and don't want to spend a lot of time downloading something only to find out in 10 seconds its not for them.
Even if you don't like/enjoy a project always remember to respect and give constructive feedback!
