This website contains age-restricted materials including nudity and explicit depictions of sexual activity.
By entering, you affirm that you are at least 18 years of age or the age of majority in the jurisdiction you are accessing the website from and you consent to viewing sexually explicit content.
Yeah no worries.
The issue is that as rules get more specific, those types of users/trolls go out of their way to skirt around the edges as closely as possible without breaking them, and usually very vocal about not breaking the rule in the process.
On the flip side, vague rules means moderation can be viewed as simultaneously both heavy and light handed depending on perspective.
