Academic in this instance. It would be an absolute disaster for Vine to assert or cooperate with a Weev-esque prosecution for something of this nature.
You clearly have no concept of how trademarks work or even what they are, and your callous attitude toward them is not only going to get you into legal trouble, but is incredibly antagonistic and off-putting. I'm not sure what you were expecting to get out of making this and posting it on HN, but you will find that your attitude has done nothing but garner you a lot of ill will in a community that you were clearly trying to impress (and have failed spectacularly at doing so).
I'm sorry for coming off that way. I just hate the fact that all you guys are coming off extremely negative and then wondering why I'm not responding the way you want me to. I've dealt with a thing or two in my career my friend. I'm not trying to impress the HN community by any means, I was simply posting a link to something I made. I don't live for HN, and this is clearly not a startup along the lines of HN. All you guys need to relax. It's all water under the bridge to me. If I get a C&D letter, I'll deal with it then. At the moment, the client is up and running and that's all that matters. Thanks for your input.

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.
