The problem is the scammers try it with just misspelling the name a little bit. The one(s) with more Zz's I've seen before.
It's the internets. There'll always be scammers and people trying to use other people's reputations. Report whoever you catch and tell all the kids to be careful...on the internets.
Unless someone tells you they're logging on their alt and who that is or they log on right after your friend logs on and continue your conversation, don't believe them.
