I get some friend requests from people I don't know. It's no biggie... I just let the request sit there unanswered. I suppose maybe they were authors and I should consider sending them a message, but I really only want a certain type of person on my FB, namely work and school friends. Not family, and not strangers. Anyway, there's no way I'd consider the author's behaviour "abusive," I mean get a grip. A level of faux-sensitivity seems to come into play with internet users.
