Most of the sites nowdays have porn problem- Instagram, Pinterest, Twitter of course Tumblr (Tumblr was ok with it – at least until they sold to Yahoo for $1.1B)
When sex.com launched -they had taken the pinterest concept and applied it to sex and porn. That made the site skyrocket. Sites like twitter facebook, pinterest and isntagram have porn problem as well.
Just few days ago LinkedIn changed their privacy settings and kicked off all sex workers, prostitutes and other people connected to adult industry, They even went as far as eliminating the word Hot off the profile – don’t know if hot gossip falls under that category. They sure do not spend much time doing their research but use the automated version instead.
