If you’re wondering why some of your posts are suddenly marked as NSFW out of nowhere (I had a car post marked as NSFW, bizarrely enough), it’s because Tumblr has in place a rather imperfect algorythm that means that if a lot of NSFW blogs reblog you, a post is labeled NSFW. 

I’m sure it will be a little while before they iron out the kinks. In the meantime, don’t freak out. And if you get posts marked NSFW a lot, it means you are probably very popular!
