It's actually a pretty good point. As long as you're not impersonating someone else, you should be able to buy and sell account names.
You are only allowed to post 2 times a day, content that is 300 words or more, not post in the wrong place, not say the wrong thing, not have any ideas that differ from whales, and not make any errors or slip up in any way, as if you do, you have labeled a plague on the community right away. You should power down and leave after being insulted and attacked.
Although I agree that this sometimes happens, I've found plenty of helpful people and healthy disagreement on HIVE. I'm personally stacking and powering up ALL my HIVE to counter centralization of voting power with the few whale accounts.
