Lol, interesting. Although I wouldn't condone this type of deceptive behavior, you should consider that at current prices 50,000 SDC is only about 8 BTC. The reason why the distribution would be bad at this point is because the market cap is so low at like $330,000. It doesn't take much to buy a lot of SDC. As the price goes up people tend to sell some of their stash and distribution becomes more even.
