> “By default, messages from friends or friends of friends go into your Inbox. Everything else goes to your Other folder So, your email service works in this way that's completely unlike every other email service in existence (where all messages go to the inbox unless you tell them otherwise), and it's the users' fault for not understanding it?
Facebook knows most users don't want another email account that is just going to get filled with spam. So how does Facebook deal with spam? Simple, it puts it into your Others folder. Otherwise you get users complaining about spam in their messages.
It doesn't sound like "Other" was meant to be a spam folder. If that's the case why didn't they just call it "Spam" and install a spam filter to send mail there?
