Fantastic! I woke up with morning with 10 SPAM messages from Facebook in Chinese!
Looks like spammers are creating Facebook accounts with email accounts they find. Of course, I didn't confirm the Facebook account.
Instead, I reported it to Facebook to have it disabled immediately. You can also send an email to firstname.lastname@example.org for more information.
However, it's interesting how I was able to receive these SPAM messages (below) before I even confirmed the Facebook account.
Hopefully, this will do the trick!
