Maybe y'all could make an 18+ Photography Community together. It takes a lot of work to moderate and curate a community once it gets large or active enough. Having clear guidelines about what the community is for and how to appropriately use the community will help leave no excuse. You will find those porn folks posting at some point and keeping an eye out to make sure it's not just a shitpost porn dump probably won't be as tough now as it use to be. Just an idea for y'all. If you can't find a solution... make one.

p.s. I love this model's hair!
