What's the agenda??? Why youtube all of a sudden?

Curious why are we getting bombarded with questionable content from YouTube? Three topics in the front page all dealing with questionable content from the tube. And this isn't a discussion on the videos this is " this is questionable" then boom 3 or 4 fucked up links being posted here? What's the conspiracy??? Who lets their kids here watch youtube? Why?

No one else find it weird all of a sudden three threads pop up at the same time dealing with the same content.

Edit: 4 threads on the front page

Double edit: Not a user that posted them has been here for a year. Three of them joined around the same date.
