AceShowbiz - Even such beloved star as Rihanna didn't get an excuse from Instagram for posting a racy photo. The Barbadian songstress' account was briefly suspended in 2014 after she shared a picture that showed her naked backside. Her account was quickly reactivated with the photo in question being removed, but the "Umbrella" hitmaker took down the account, probably as a protest to the company's nudity policy. She moved the show to Twitter before eventually returning to the photo-sharing platform six months later. To this day, Rih still often posts her sexy pics on Instagram, though she manages to comply with the platform's guidelines.
