I want to remove this Permalink option, which shows up on the blog, once I moderate the comment. Please help and guide me step by step in removing this as I am relatively new to the wordpress.

I was able to remove it by adding the below at the end of style.css file, but since the last update of my theme I am unable to hide it, hence please help.

.comment-permalink{
display: none !important;
}

Thanks!
