They do and they do it a lot. That's why since 2004 changed lines and other poossible contact points are suppressed in the default output. The problem with misdirected complaints was getting bigger than the spam problem itself. You can filter spam, but you can't easikly filter complaints. Or at least it's not very nice to filter them.
