You can kinda do it with Google Customizabe Search Engine, which is basically a thin wrapper around Google. In a regular Google search you can use syntax like -site:ignorethisdomain.com to exclude specific domains (i do this with Pinterest whenever searching for images, for example). But manually typing in a large list of black listed domains would be tedious so instead you can set up a CSE with everybody you want to ignore and then just use the special URL as your search engine.
