I wrote a plugin similar to this a long time ago because uBlock couldn’t do it, at least not efficiently. I mentioned it in another comment already so I won’t repeat everything.
The thing I made turned out to work better for getting rid of links you never want to see (facebook, twitter, quora, etc). You can apply whatever CSS you want to matches, so you can blur using a transform, redact (color: black; background-color: black), hide (visibility: hidden), remove (display: none), etc.
I even showed it to gorhill but I don’t think he looked to hard at it and suggested I try something in uBO I already knew didn’t work effectively.
