If you make that point when they give asshole answers, they usually help or they just leave you alone. Not the best way of dealing with them, but it works.

I remember experiencing a downvote spree that lasted for about a month. Literally every single question I asked got downvoted. I was furious at first, but then I found it hilarious to the point where I ended every question with, "All set for downvotes!", or something of that nature. Some people are just pathetic.
