Yes i noticed this as well and have a lot of them on about 6 of my sites, i also noticed a lot of my competitors in the search results have them as well, some of the ones i have were deleted or page gone.
I thought it was mostly targeting the cam section but it turns out some mainstream sites on another forum i am with, they are getting it as well.
I should add i noticed some of my sponsors have them on their main sites as well and i told them last week about it.
