Well fortunately they didn't catch my account. And I'm happy they didn't. My fake account allows me to:

1. Login to websites that I don't want to share my actual contacts to but just my real name (my fake account has my real name and my real account a fake-ish name so that I can't be Googled too easily).

2. Disable that annoying wall by not having a lot of friends.

3. Be part of meaningful groups (only 1 so far), because my friends know that I have this fake account with a real name.

4. Amazing account for demo purposes when I was working at a coding school.

5. My fake account is setup on auto login on my primary browser, so if I type "fa" and press enter, I feel bored by the empty wall and very tiny friends list, instead of engaged. My main account is auto-logged in to messenger, so that's where I go now.

I'd be betting that they are going after huge blocks of fake accounts that they can link together somehow. Someone like you with a single fake account, they'll live with. They probably know that's so and so's other account. He likes to use that one on his PC. ;-)

I bet Facebook links your fake account to your real account internally and you count as 1 MAU in their stats.
