Please stop reporting all OF models as spam. If a post is off-topic, report is as off-topic. If community rules forbid OF models from posting, report that. If a user is flooding a sub with multiple posts a day in a row, that’s a legit report as well.
Otherwise a post by an OF model is not in and of itself spam, even if it is made by a <ferengi>female</ferengi> with the temerity to control her own sexuality.
I have a simple solution to this: If you are the moderator of your community, just put a rule in the sidebar disallowing OF links and references. Handle it on a per-community level.
I just wish c/gonewild would hold true to what made r/gonewild special. Allowing people who monitize to post there just turns it into a generic porn subscription.
The downside of that is that a lot of OF content is posted to dozens of communities and this fact is the main spam problem with them, not necessarily the content in any particular community on its own.
