Warning: if you’re a swimsuit supermodel who likes to pull the dance moves, don’t you dare post a video of yourself getting down on YouTube.

It just might get banned.

Accidentally.

This week a one-minute clip of Sports Illustrated cover girl Kate Upton gyrating and bouncing in an itty bitty bikini, demonstrating how to do the “Cat Daddy” dance while on a magazine shoot, was yanked by YouTube for violating its nudity policy, despite the fact she was not naked.

The video was later brought back to the video sharing site on Wednesday, but this time with an age restriction.

“With the massive volume of videos on our site, sometimes we make the wrong call,” a rep from the Google-owned YouTube told FOX411’s Pop Tarts column. “When it's brought to our attention that a video has been removed mistakenly, we act quickly to reinstate it.”

Apparently the age restriction was a mistake as well, because by Wednesday afternoon, it had been lifted as well.

The video sharing site has allowed videos of other stars like Selena Gomez, Justin Bieber and Chris Brown doing the exact same dance to remain up and unrestricted. So was there a double standard going on, at least before the “mistake” was resolved?

In other words, if you are busty, blonde and wearing a bikini, are you not allowed to pull some sexy, club-like moves without red flags being raised?

“I seriously do not understand how a girl dancing – clothed! – violates a nudity policy. It seems that YouTube has a very large and inexplicable grey area for what they consider ‘too sexy’ and that ‘too sexy’ is just as ‘bad’ as ‘nudity’ and therefore violating policy,” said Amelia McDonell-Parry, editor at entertainment/pop culture website TheFrisky.com. “They should really give more specific rules to their users: ‘No sexy dancing in bikinis if you have larger than C-cup breasts!’ Ridiculous.”

Reps for Upton and Richardson did not respond to a request for comment, and a rep from Sports Illustrated while declining to comment on the incident, told us the magazine wasn’t involved in having the video banned.

Phew.
