Add-on suggestion: screamer website blocker

Sorry if this is in the wrong place.

So I just got jumped by a screamer website, being the third time ever as far as I remember. So I had an idea: would it be possible to create an add-on that prevents screamer websites from loading (sort of like the “dangerous website” message that is built into browsers), thus saving people from having to buy new underwear?

Say if someone encounters an undiscovered screamer website. They could then report it on a forum or something. It gets reviewed, and if correct it gets added to a list of websites for the add-on to block. This way anyone that has the add-on will no longer have to deal with that specific screamer.

Maybe better way would be to create a new filter list for uBlock (or other popular adblock), maybe there is one already.

Adblockers these days blocks much more than just ads.
