When it comes to hosting a community like this that hands off policy when it comes to communities that reddit did for a time is not something we can repeat. I generally disagree with such community building ethos in general, but for a NSFW community that's trying not to implode the high probability that exploding-heads would cause issues serious issues against minority sexual communities here in the same way they have on other instances is not something I feel we can risk. Even more so, their content is poorly moderated in general and we aren't too sure where we are going to move hosts either. On instances that decided the same approach you feel, it has backfired hard when they have raided communities and began to harass and brigade people. Such cases are recent as well. I'd have to double check the modlog but I'm pretty sure they've already caused issues here as well on a consistent basis.

TL;DR: I don't want to set myself up to having to clean up a bunch of gore and NSFL images being posted into communities on here.

This is reactive, not just proactive. The history of exploding-heads is known.
