I have upvoted this post. Because i believe that, regardless of your motivations (which are misguided), anything which brings people and money into the steem ecosystem is a positive thing.

that said, i wanted to clear up one thing that you might not understand completely:

(if you look at their accounts they don't even post most of them) except for one or two

This doesn't necessarily mean anything sinister, except that one person owns many accounts. There are a variety of reasons that one person might own a main account that they post with, and other accounts that either come from mining or other endeavors that they do not use to post but that hold a portion of their steem power. As an example, in addition to my own upvote with around 8000 steem power, i also upvoted your posts wiht approximately 20 accounts that hold aroud 400 steem power each.

Because of the way votes are calculated, holding your SP in many accounts affords no strategic advantage over consolidating it.

What this does mean is that the number of downvotes does not necessarily reflect the number of people that actually feel a post is worthy of a downvote. For example, i suspect that most of your downvotes (aside from mine) for the post that got 10 of them were the same dude.
