Facebook bans users from saying if they’re a ‘top’ or ‘bottom’
The new content policy makes things like saying you’re a ‘top’ or a ‘bottom’ off-limits, in a move the social media behemoth says will combat content that “facilitates, encourages or coordinates sexual encounters between adults” and bars “sexually explicit language that may lead to solicitation.”
“Sex positions,” “sexual preference” and any number of other sexy umbrellas pertaining to “sexual hints” are all means for moderator intervention now.
Another common phrase you see a lot — “send nudes” — is a no-no, whether its meant as a joke or an actual request. The new rules ban “offering or asking for nude images.”
