Strike through username

Hello, 

         I have a usergroup for Banned Members and I want their Username to appear with a line across as such: Eugeo Ayano 

I was told to make a usergroup for the banned members and choose a color for it then add the Hex of that color to this CSS code but it's not working. 

Code:

span[style="color:rgb(0,0,0);"],span[style="color:#000"] {text-decoration:line-through}

Any help will be appreciated.
HAPPY HOLIDAYS!

Try this here.

Code:

a span[style="color:#COLOR"] strong {text-decoration: line-through;}

Works great. Thank you very much. 

This is solved.
