content: Is there something like a "block MSM" extension or add-on out there? Or even just an easier way to automatically filter out abc/cnn/bloomberg/forbes/nytimes/wapo/npr/pbs/msnbc/cbs/disney/vox/vice/slate/rps/etc. from my search results without having to remember to do/add a giant "-cnn -abc -cbs ..." to the end every time?
