Yes, but adding a list of sites to remove to every single query you ever type... search engines should just remove bad sites (note: I am actually against removing Quora, this is just about the general case). Also, there is a maximum input length for some reason, so that might not actually work.
("For some reason" -- to prevent monster queries of course, but I mean, removing sites doesn't cost much computational power at all. With some literal quotes and AND/OR operators you can create short queries on which it basically times out after 5 seconds and only returns a few dozen results that it found so far, and when you reload the page, there are suddenly a lot more results. So it shouldn't be limiting input length but complexity, which it already does by timing out.)

I actually didn’t know that. My first thought was a browser add on that allows the user to blacklist domains they’d rather not see results and construct a query based upon.
Seems like that moot if a sufficiently long list would result in sites being left off and end up in queries anyway.
