Yeah DV trails dont give you a chance to consider if its spam or not. Im not on any DV trails with my @solominer account. That way I can make a conscious decision on what to downvote.
And its not their stake in many cases, its leased. So they did not buy into Steem, they are just renting it. Id rather downvote crap content than allow it to pay out and lower the price of Steem.
Id much rather see just 50 people writing quality posts, instead of allowing everyone and anyone to bidbot their posts into trending and then making a dash for the door with their earnings, lowering the price of Steem.
