I am creating a website where users can review and rate content creator's paid content. Think of it as a yelp for patreon, onlyfans, etc. However, in order for this website to gain traction, there must be enough users providing reviews.

So i am wondering, how do people here get users to generate content for their apps/websites?

I tried to post to some subreddits related to this topic, but i feel like most subreddits have rules against this stuff. (I actually dm'd a mod directly to see if I can post and ask for reviews and they just proactively banned me from the sub)
