the website namecoin.org he's squatting on
Namecoin.org isn't squatted. It's clearly actively being used to promote the Namecoin project. I think the website looks good.
I wonder if he declares this kind of income at least in front of the tax office.
How fucking tacky of you... Get a life and find something more productive to "wonder" about.
If you don't like Namecoin, contribute code or don't use it. If you don't like Namecoin.org, make Namecoin.io or whatever, but personally attacking someone that basically works for free is bullshit.
