Another thing that Cohost has figured out that Tumblr, Twitter, and YouTube haven't is that encouraging users to categorize nsfw content without punishment does more to reduce porn spam than an outright ban on nsfw content. I have not seen a single nsfw image here without willingly clicking past filters, meanwhile browsing any trending tag on Tumblr was like walking through a minefield. And I couldn't even fully blame non-bot bloggers for not properly tagging their posts, because the community guidelines were so strict yet vague that they could get banned for breathing on the tag field wrong.
