How to avoid a user profile blockade on Facebook.
Think about the following factors:
1. Use your personal name!
2. Authenticity is key!
3. Do not spam your profile! Use Facebook Fan pages!
4. Do not change the name displayed (from your profile) too often - may cause blockades
5. Do not add too many friends per day - may cause blockades as well
6. DON'T BE TOO ACTIVE ON FACEBOOK!!! [They] May block you as well :)
