We put together version 0.0.1 of a plugin to silently kill spammy websites in your Google, Bing and DuckDuckGo search results. It’s an afternoon project so it’s not exactly super polished, but maybe someone is interested.
Or is like us and hates PerlMonks enough to want to make them disappear forever. That’s more of a pet-peeve though, we focus on sites like Lifehacker.com, About.com and Goodreads.com (it has reviews for books that haven’t been written yet).
If it sounds interesting, you can grab the .xpi file here.
I should mention that unfortunately it’s a Firefox only plugin, it’s not signed for Chrome loading and since it uses the JPM builder instead of the unsupported CFX.. it.. doesn’t run in Pale Moon either.
