why should I do this?
I'm not acting like a sheriff on the blockchain here. In addition, I don't think that I should distribute downvotes here and that is not my job here either.
But you seem to have this role written on your chest. However, you seem to make huge differences between people you like and people you obviously dislike.
If you already believe that you feel responsible for reward adjustments here on the blockchain, you should do the same to everyone (including people you might know.) Because if we are all equal here, then you should also treat everyone equally.
