NaI & Stig...
Both say NO to deactivate
But Stig says defriend is OK?
Do they get notified?
There is no notification when someone defriends or block you, you'll only know if you notice that you're no longer seeing any of their status updates or them vanishing from your friend list.
I've only "caught" someone in the act once, one moment they were online and the next suddenly they vanished from the chat list along with all their status updates in the newsfeed. Usually I only notice the friend count went down by 1 and sometimes can't figure out who went missing.
