I'm not seeing it, I selected some of today's trending topics and did scans for Hernandez but returned no porn, and I used my porno account. Did the same on my sports account, nothing. Does that mean that twitter cleaned up all the feeds in one day, I would think not.
I think there's more left out of that story, like what type of account does this guy have (the author that is), and who does he follow and who follows him. Remember, twitter does a good job of matching likes and following within' your related interest. Sounds to me as if this guy has some shady followers, as well as you know he's looking at a bunch of porn as well.
Not certain how newsworthy that is, but I have noticed one thing lately about twitter, with respect to searches. Searching porn star names used to bring their twitter account and related social media feeds at the top, no when searching for specific porn star names you have to include 'on twitter' in the string.
MILF porn star Cherie DeVille will not generate twitter feeds, MILF porn star Cherie DeVille on twitter, will. Go figure, things is always a changing
