Soooo yeah, companies have things called "trademarks" and "copyrights"... you can't just go putting another company's name inside your company's name, and then make your imagery the same as theirs, without their lawyers sending you a strongly worded C&D. However I don't see why this would have to shut down based on that -- why not restart under a new, distinct name and branding?
Though you don't seem to be using Vine imagery... why wait for the inevitable?
Most hosting companies won't share your bravado.

Hm.
They're ranking 2nd on Google for the term 'vine', and even have the Vine logo as their favicon and next to their listing!

The point being that although security through obscurity is recognized as a terrible way to secure anything, it's still a basis for the CFAA.
I don't think the Vine people are such terrible people, but please realize they have you by the balls if they so please.
