Amber Rose Posts Bottomless Pic on Instagram to Help Bring Back the Bush

Amber Rose bushwhacked Instagram's no-nudity policy and got the photo removed, but it still lives on ... as does her campaign to "bring back the bush."

Amber pushed IG's boundaries late Friday night by posting a bottomless pic of herself ... and it was deleted within 2 hours. It didn't matter though, because her "fire ass feminist post" had already been picked up ... plus she posted on Twitter too.

Rose added a reply to the pic's removal shortly after ... claiming she didn't give a f*** and making her intentions perfectly clear.
