>>460861How would the extension know that the specific content among other is porn? Filters block entire sites because the makers of the filters or lists know or assume that those sites are pornographic, like blocking Youporn is a safe bet. But again those programs block from simple lists made by humans, not because they themselves could recognise the content.
Like on here you could simply block the NSFW boards, but this is trusting in that NSFW content will only appear there. If some porn should manage to slip through to a SFW board you still will see it. You can block it THEN by hand, but not beforehand or you have to block an entire board to be sure.
