There is no server behind what you see, and your key stays on your PC and never goes through the wire. But if I was evil, I would be able to, let's say, send myself the posting keys of everyone who tried DTube so far?
What would I do with it? Upvote myself some more? Post shit content using your username? Meh, not interested. In any case, I am asking for posting key only so that risks are limited. If I was asking for password or active key, then you should beware, as I would be able to steal money. Feel free to read the part of the article where it talks about 'Why I cant login with my password'
Brilliant! Thanks for the response and playing the devils advocate!
This is really exciting what you have created here!
