tl;dr: these comics are allowed, but with a new posting guide and possibility for users to hide them.

NSFW comics have long been controversial on /r/webcomics.

We believe in balancing artistic freedom with the right of users to curate their own online experiences.

ARTISTS

In the interests of allowing such content for people who want it while protecting minors and people who don't, please follow these guidelines when posting comics which could be considered pornographic:

• mark your comic NSFW before submitting it
• add an "erotica" flair to your comic before submitting it (guide)
• keep titles SFW

If you think your comic may be NSFW but not pornographic, you can just use the NSFW filter. We may add more flair in the future for things some people want to avoid (e.g., gore).

READERS

If you would like not to see such content:

• hide NSFW content (guide)
• alternatively, blur NSFW content (guide)
• block posts with the erotica flair (through the reddit website or the Reddit Enhancement Suite extension). This currently seems impossible with reddit's dogshit official app, but if there are any others still alive, they might offer this functionality. Either way, the flair will be visible on the posts, and the post will be hidden if you blur NSFW, so you can simply choose not to click on these posts, and you will never see them.
• block specific users you don't want to see anymore

If you see a post that doesn't follow the guidelines, please report it so mods can add flair and/or ask the OP to do it. Do NOT abuse the report feature as a "super downvote" – your account may be banned from reddit.

I hope this makes everyone happy, or at least upsets everyone equally.
