Is today your first day on the internet? Porn is popular. Older outlets like tumblr have been actively squelching pornographic content. Places like Steemit are alternatives people can pursue.If they properly tag it as NSFW, we can block it. If they don't, we can downvote it.
Thanks for changing your down vote to neutral - I have blocked NSFW because I have a life & am not interested. Most people do not properly tag there porn on d.tube.
