Is this something you know from the inside, or your (probably good) guess?
I would imagine there's a lot of porn, sex work, stuff Verizon is trying to wash its hands of lately with Tumblr.
EDIT: Ah yes HN - where admitting that you're just speculating wildly like everyone else gets you the downvotes -_-
If you had started with “Not related to Verizon in any way, but IMO...” that would have been perfectly fine, but given where and how you made the statements it looks remarkably like you were claiming inside knowledge of the situation, and then feigning innocence when called out.
