It's my desire Hive account@markkujantunen.

And it is my desire to downvote these posts.

Who are you?

A stakeholder on Steem.

Are you my servant ?

No.

Why you downvote me at any reason? I boost my post from my own opinion, it's not your father property.

I downvote your posts because you're a spammer who puts out posts containing nonsensical text coupled with stock images. Your content is pure spam and I wouldn't be surprised if it was generated algorithmically. It's there for you to buy votes on it with a positive return on investment, which was a feasible strategy to milk the system before Hard Fork 21 but no more. Posts like that get downvoted into negative ROI territory until you decide it is futile to continue because it costs you money to do so.
