What's really limited is the amount of rewards that can be distributed. By downvoting low effort posts like hers, anyone else who may have put more work into their posts will get more.
And just because you don't look at the upvotes, doesn't mean they don't exist.
We have seperate teams actually, and only use the free downvote power to downvote. Which it seems you don't even know exists - or why it does. Complaining is easier than learning, I know.

And that you try to use your witness voting power to influence how we use our votes says more about you than it does about my qualifications as a witness.
