The rewards we get here come from individual effort connected to the recognition we receive from other users and different projects. Therefore, what we get is ours and we have the right to do whatever we want (no rules here, I think). This is called freedom (and it is not something negotiable).
However, these rewards come from a plural space, where everyone needs everyone else (no exceptions), so... All users should have the minimum common sense to keep a good part of their own HIVE POWER to themselves so they can help the ecosystem itself using their own judgment before voting.
