A good question....
If you sell equity shares in something.....a product, business, item, etc, then you are legally obligated to the people buying said equity shares.
In the US, selling equity shares is regulated by the SEC (securities and exchange commision) The sec is higly regulated by the government of the us. The have very strict rules about what is and isn't a company that can sell equity shares of itself.
To be blunt, the company that is in charge of the DOT tv extension, Demand Media, is not even approved by the SEC at this point.
For any compay to do business inside the us borders involving equity shares of ANYTHING, they need to work with SEC to be legal. This company is located outside of the US, and worse yet in a country that is not exactly known for square dealing.
They have ZERO obligation to any laws othe then Slovakian, and in reality have FAILED to prove that their contracts even apply to Slovakian laws.
There was even someone in the thread linked that gave $50 with no respnse, no return, and no reply from the company...
Quite frankly, I would consider anyone giving them money in any form and easy mark.
