It is what it is, sometimes you'll get feedback for why votes went one way or other, most times not. If you're trying to be helpful, and aren't a jerk about it, you'll garner positive votes pretty easily.

I do remember something I thought was weird when I was new to the monastery, it seemed like I would instantly get one negative vote as soon as I posted, I never pursued how/why that was happening, but if that's what you're seeing, I think you can ignore it.
