Steeming according to a Code of Conduct is really important. It's the wild wild blockchain and there are no 'laws' governing, except the power of words and upvote/downvotes. If everyone adopted some basic 'rules of decency', Steemit would become a much better place.

Use upvotes to bless other people. I try to use 90% or more of my upvotes on others.

I especially agree with this one. We can check ourselves and others using steemreports. Nothing is hidden on the blockchain: http://www.steemreports.com/outgoing-votes-info/
