Is a troll really bugging you? Has his/her idiot behaviour just taken things too far?
You can put the person on Ignore but then you still see his/her name everywhere and you see that there are posts by that person. Even quotes showing the actual posts by that idiot!
So Jan showed me the way.
Get this script:

Then install it it using
Tampermonkey for Chrome
Greasemonkey for Firefox
I will post some details on how to install it over the weekend.
It's like the person doesn't exist and you can smile knowing that you don't have to see the troll's name again.
