Instagram is home to plenty of scantily-clad models and edgy memes that may start to get fewer views starting today. Now Instagram says “We have begun reducing the spread of posts that are inappropriate but do not go against Instagram’s Community Guidelines”. That means if a post is sexually suggestive, but doesn’t depict a sex act or nudity, it could still get demoted. Similarly, if a meme doesn’t constitute hate speech or harassment, but is considered in bad taste, lewd, violent, or hurtful, it could get fewer views.

Specifically, Instagram says “this type of content may not appear for the broader community in Explore or hashtag pages” which could severely hurt the ability of creators to gain new followers. The news came amidst a flood of “Integrity” announcements from Facebook to safeguard its family of apps revealed today at a press event a the company’s Menlo Park headquarters.
