Can you ban viewer bots on Twitch?

I've been streaming for a while now (about 1 year ago) and I always see these viewer bots like "Commanderroot" "slocool" "CommuntityShowcase" "anotherviewer" and many more in my viewer list. Can you ban them from coming into my stream? Schonmal made it at a few, but did not seem to work.

Why do you want to ban them?
