Well there's "quitting" and "stop using". I have friends who've quit and told me, etc. I also have friends who just went dark. I don't have updated non-FB contact info, because all our comms had collapsed onto FB - or were only ever FB. Their last post was in 2015 or 2016, and they obviously don't reply to Messenger. They just stopped participating one day.
