I am always sure to vote 30witnesses. Actually updated one the other day (helpie dropped out ).
One thing I do when I give someone an account ticket is set me as their witness/proposal proxy and of course recovery (this is automatic).
I think some of the bigger accounts giving away lots should consider this.
If you feel it is controlversial, warn them first amd let them know they can change it using steemworld or something.
That said I think we can easily get 70million sp just looking at the whales and orcas not voting. A few of the big guys are operated by ???? And may not be allowed to do anything, but chasing minnows and plankton will be difficult to reach the target.
