No matter what they say, they are not Joe Bonamassa. Duplicate profile scams are the reason that Facebook started their “Verified Profile” system. Here’s a link to Facebook’s official announcement about the verification system: https://www.facebook.com/help/196050490547892
Notice the little blue check mark next to Joe's name. This is crucial. If the profile doesn't have this check, it's definitely fake. Notice that Joe's official Page & Personal Profile are both verified.
We at J&R Adventures, Joe Bonamassa’s official record label, are saddened and angered that we had to create this page, but con-artists will never stop, and though we work closely with Facebook to kill fake accounts, scammers will create them as quickly as we delete them.
