I hear you, however If within my first 30 seconds on here and I can identify a handful of culprits then there must be an easy way to find them in bulk.
I would start by banning the ones that obviously do it and send a message to the community that it won't be tolerated.
I'm sure the programmers are aware, I'm still trying to find what they are working on for future releases. It would be very good to stop these bots, if we want Steem to really grow.
