I have seen this question a thousand times. Hivewatchers are not here to educate people; they only want to attack them to go out of the platform, perhaps because they don't believe in a decentralization ecosystem. They had a delegation on Steemit Inc for several millions of SP, so they lost their power and authority here. Besides, Blocktrades is proposing decentralized blacklists, so you can select which one to see while blogging.
Regarding your question, everyone has the right to use, sell, or give away his tokens. It is not logical to earn rewards if you never will enjoy them.
