Botting someone without knowing their content is a problem which is plaguing Steemit. Many people like someone's post(s) so they bot their asses up. Later, if these botted users start posting trash, they still get upvotes.
Your posts are great!!
It is a shame that you do not have steady support for your votes. I think that such steady support is crucial in keeping loyal, quality content creators!
Creators get frustrated when their rewards are like a gambling rollercoaster. Uncertainty tends to bring stress.

I will follow you from now on. And when I say following I mean that I will actually upvote your posts!!!
(some users say that they will follow you trying to make you follow them back to upvote their posts while they never reciprocate with votes).
