I had an account at Vimeo removed some time ago. It was bizarre to go back and forth about why. They had playboy and other nudity on site, we pointed to that being more nude than what we had published (which was sexual in ways, but no nudity) - and this was a paid / upgraded / pro account - a few hundred bucks. Long story shortened they said their determination was based upon a site linked or mentioned in the videos / profile that had more explicit content on a subpage. So it wasn't the videos we made specifically for vimeo publishing (wasted time and money) - but part of what had been promoted was against some editorial something or another.

I pointed out content on their site that was way over the line of what they had issue with on that sub page - and they said something like 'don't do as they do, their (other accounts on vimeo that were not banned) stuff was not indicative of what was okay on vimeo'

All in all it's fine with me, they can do things however they want, it's a privately owned site not a gov portal, it was just so frustrating trying to make content that fit and going through so many things only to get banned for some unwritten rule.

So I used to recommend them over youtube, but that was a long time ago. Now I strongly suggest not to use them or depend on them for anything.
