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.
The German gonewild community banned all commercial posters. Even an onlyfans link in their bio will get you banned. I think the community is still thriving.
My wild guess on this is, that you can go wild in Germany and still have time to do your daily job. And because the german society is not so focused on money in terms of: if you do not have it you cannot get basic necessities like medical interventions or learn a job.
US content creators have a big incentive to monetize everything to the maximum possible.
Edit: germansgonewild has a maximum of two posts in 24 h and a profile wide ban of paid content. No links, no comments etc.
