It’s not clear to me what you’re asking for. Are you asking for an update to the rules to disallow any content that is advertising for their Onlyfans and similar sites?
If you’re asking for a full ban on that, then there will be very little content posted to the sub at all. I’m not keen on the advertising dynamic, but there’s also a large amount of flexibility in how the models choose to interact with the community. There are certainly some that spam or make it clear that it’s just an agency posting on their behalf, but on the other side of the coin there’s also quite a few who are very respectful, engaging, and contribute to the community in only positive ways.
Overall I think a good middle ground has been found that allows for a good amount of content to flow into the community and for quality contributors to thrive.
I definitely take note of posters who have dozens of posts, but don’t reply or comment. It’s pretty common to see accounts with 0 comments and I’m less likely to engage with their content.
Concerning verification: Agencies can just ask the models to take a verification shot and the fake/catfish posters will just post in a different community in the instance. Requiring full verification is such a large barrier to entry for new non-commercial posters that they would probably just not post instead. That’s not even mentioning the administrative burden on the mods. The structure of this place doesn’t lend itself well to that requirement in my opinion.
