It's basically just a filter we need.
There is a blog where people can write comments.
As in every blog, there are people just messing around - you might know them as "trolls".
So the "normal" people want a filter where they can block different users whose comment they don't want to read."
Give me a competitive price, and the project is yours.

I think an add-on is a bit overkill for this kind of request. Would a greasemonkey script do it to? If so, send me the link to the blog and you get the script a few hours later. Thanks.
