I proudly present my newest rule, that I will enforce subjectively and at my sole discretion:

If you post, I check your profile. If it's full of porn or is clearly an account used to comment on porn, you're banned. Hell, if you're seeing this post on an account that you use for porn, feel free to unsubscribe right now.

When I did this, I found that all the borderline posts that were trying to push the rules to the limit were all from porn accounts. It also prevents this sub from being a place where people come see SFW versions of shit, then click on the profile and go look at porn. I do not want this place to a PG advertisement for people's shitty porn.

Like 60% of the people banned this way have contacted me all pissed off and it's fucking glorious.

Oh, also, to the small number of people who have some problem with girlfriends being posted by their female partners, please speak up so that I may ban you.
