@ausbitbank - Has a lot of Steem, doesn't do shit besides whine about vaccinations and other conspiracy bullshit.
@blocktrades - MASTER of ripping off the Steemit community - sells delegation, rapes you on his website, etc. etc. etc. He also flagged this post rather than reply, saying a lot about his position here.
@thecryptodrive - Another one who runs a scammy ass service and does nothing to contribute other thank taking your Steem/SBD.
@smooth.witness - Has never really contributed here other than raping the Steem/SBD market. Donates to a few things I hear?
@aggroed - Another "community" guy...loves to circle-jerk those who can give him big witness/post votes but deep down inside, he wants to be genuine.
@lukestokes.mhth - Has never done ANYTHING to contribute other than run a bullshit automated post of transfers.
@clayop - Supports the Korean community...avoids other races at all costs...
@someguy123 - Does some development stuff, good. Runs an account creation service (since Steemit, inc. can't get their shit together).
@pharesim - Promised some nonsense he never delivered, doesn't do anything now...
@anyx - Contributes a LOT to keeping Steemit clean from spam and scammers.
@netuoso - Contributes to many projects around Steemit.
@followbtcnews - Runs steem.chat and does some community stuff. Good dude.
@furion - Another who does nothing and never really has. (Hasn't posted in over a month)
@pfunk - Recently back in the top 20. Please do something.
Witness voting is another prime example of the Steemit circle-jerk. Do some digging, you'll see most of these witnesses with large holdings trade votes in order to ensure they stay in the top while contributing as little as possible to the Steem ecosystem.
