1. Because success attracts success. Not think a bit why you don't attract them.
2. It doesn't matter who in the circle gets the downvotes. Every member of the circle loses 50% - content and curation rewards.
3. It's my democratic right to downvote you then. Stop complaining. If you want me to change my voting, give me a reason to do so.
4. You caught attention by downvoting and blackmailing minnows. Great way to feel important!
5. I don't take orders from you, and you don't know anything about me.
6. You're just one part. One I had hope for, but that's diminished again.

Karma loves me. I don't need success, I have everything I could wish for already. So do not worry about me :)
