They are eliminating verbiage from ads, basically as a way of saying 'the less we know, the better' as far as what adults are doing when they meet each other from the dating section.
As long as the message isn't overt, then there's room for leeway...pretty much. They're just playing politics, while allowing people to, umm, do what they do...whatever you all be 'doing' with each other.

I wouldn't know what y'all be up to. I only go by what I hear.
