It’ll be interesting to see how cooperative Reddit’s user base (and moderator base) will be with this. Of course they mark certain subs NSFW by default, but I’ve come across a fair bit of content on non-NSFW subs that’s definitely NSFW; usually somebody points that out, OP tags it, and that’s that. However, if NSFW links don’t work on Imgur and uploaders just stop tagging content as NSFW to circumvent that, will Imgur have to have moderators review content as well? One thing that a lot of people miss about crowd-sourced censorship is that the majority of the crowd has to be on board with it or it doesn’t work.
