Facebook is also a "legal" spammer and it spams a lot. Had once registered with a fake account just to test some application and since then every day or so facebook sends me messages like "You might know these people" with some random guys or "You have received a notification". I haven't visited facebook maybe for a year but is still sends me messages daily. Luckily I used a separate email account for registration so I just redirected all emails from facebook to a spam folder.
