^ I wish we had a system like there here in the U.S.
I let my junk mail pile up until I have like, a whole trash bag full. then I take it back to the umm, post office and leave it there. sometimes I just write "refused - return to sender" on it and put it right back into the mailbox. on several occasions, I've actually crammed a bunch of it into a box and sent it directly to the local postmaster. let him farkin' deal with it.
