There is already this I've just moved over to premium requests
I think the key thing you are missing here is that is quite likely just how the model is posting, one picture every few hours. For some models you can verify this yourself if its a free OF page or if they have a fansly on which you can see all their post times. One that has been mentioned before is Selti, she has a fansly and without an account you can see she posts one pic at a time several hours apart
What you don't see regarding this is just how many deleted replies there were to your message, those all sent a notification to those watching the thread expecting content who are then disappointed/annoyed and then report the posts.
Comments are nice in theory but have multiple issues we see on other sites:
That's a barrier to posting that people aren't willing to put up with. If you make it required people will be less inclined to post. It is horrible to browse but would you rather nothing to browse because they didn't post anything?
