Yes. If I had the voting power to to make an impact I would, in the meantime if I see this sort of thing I report it to the original owner of the content or to steemcleaners.
Aside from that all I can think of is to check if something is original (if at all possible) before upvoting/resteeming. Hopefully over time people who don't generate their own content will simply go away as they are not making any money.. (perhaps wishful thinking on my part).
