Yea, voting for your own Post has always been OK.
As long as you are not creating a copy and paste jobbie every hour.
Now that is just greedy.
Voting for your own comments is never cool. I totally disagree with that.
But Steemit is a bit of a Jungle where the Big Beasts decide who gets the Big Votes. Survival of the Fittest and all that Jazz.
I can only suggest everybody keeps on posting good content and ignore the rest and hope for a miracle. Maybe it will get better. But knowing human nature. I believe it will only get worse.
