Most of the offending sub-reddits are way off in the periphery, you can choose what ones you subscribe to, and anyone can make a sub-reddit and it's self-policed with moderators and a voting system, so the majority of normal people will never come close to that stuff and assume that it's policed and moderated. I'm subscribed to science, news and games related sub-reddits, it's an incredible portal to find the best bits of the web, depending on what your subscribed to.
The reaction I'm seeing here is a bit like "Hey! there are nasty pictures on the net, SHUT DOWN EVERYTHING" I'm not sure how much of this is sarcasm.
Reddit is very similar to OCUK, we have an images thread, videos, and we try to stick to topic threads to keep things neat. So does reddit, on a larger scale.
I'm glad reddit removed jailbait, and I want stricter policies too.
