This is an interesting take on the website and how it functions. Personally, I believe that if the creators of SteemIT don't want people to upvote themselves, then they should write that into the code.

Way before this website came along I thought of an idea like this. You can check out my blog post about it, here: https://steemit.com/money/@sreepyeldarb/does-this-make-cents-sense-a-button-for-change

While the idea might be designed differently, the concept is the same.
