The road to body positivity has a considerable amount of roadblocks — and social media is a big one.

It has recently come to the attention of the Internet that the hashtag #Curvy cannot be searched for on Instagram. When users attempt to search for the term, they are greeted with a host of alternative suggestions, such as "curvyfashion" and "curvywomen."

While this block itself may not seem to warrant concern, the reasoning behind it does.

When asked about the hashtag, a spokesperson for Instagram confirmed in an email that #Curvy has been blocked for violating community guidelines. "I can confirm that we did block the hashtag #curvy. It was being used to share content that violates our guidelines around nudity," he wrote. "Please note that the block has nothing to do with the term 'curvy' itself."

Hashtags such as #vaginas, #clitoris, #dildo, and #bitch are still fair game, though.

While the block may not have anything to do with the term "curvy" from Instagram's perspective, it does present a problematic possibility: that images with the hashtag don't necessarily violate the nudity guidelines more often than other suggestive hashtags, but that these #curvy photos are simply more likely to be reported by users.

Activist Sam Roddick told HuffPost UK Lifestyle that this move (in addition to the continuing controversy over nipples on Instagram) is regressive because it removes yet another way of viewing women's bodies in a respectful light:

They have banned images of breast feeding, stretch marks, domestic images of menstruation and classical art works that respectfully portray nude women and now they ban the hashtag #curvy. While they allow bitch, fat slag, hookers, thin — this is not a safe platform for women and especially young girls (as we all know Instagram is populated with nude images of young women effectively selling themselves sexually).

And though this move will surely rub many people the wrong way, it's unlikely to change — Instagram has thus far stood firm on all of its policies, despite any public outcry.

But seriously, Instagram. Get it together.
