Thats the way it is. Small minnows want to get upvotes by whales. I think the more SP you have the more such requests you will get. You cannot stop this. You'll have to find ways to quicker decide what to look at and what to ignore. Its not always easy to find the good content.
Just my opinion.

Edit: and just to clarify: what would a single full upvote of you get me (and for most minnows)? It would get me more sdb than i got from all posts and comments last week.
