I'm sorry I just can't imagine a user exploring a site and instead of simply bookmarking it, they press back 10 times to save its location in the serps - maybe I'm being narrow minded, so please someone explain to me how they see this happening?

I can see the block feature working - user searches for widgets, finds a spam page and backs out, quickly blocks this from results and moves on until they find the site they want.
