I've got 34 fake Facebook accounts now, and counting. They all have "lives", they all have friends, and so far Facebook hasn't removed a single one of them. None of them are real, none of them have phone numbers. Some of them are used simply to prove a point to various friends that they don't check who they friend too closely, and I use them for websites that require Facebook logins to comment.
i think facebook has tacitly allowed these types of accounts for testing/anonymity etc. you probably wont be shut down unless you do something egregious.
