As an update, I made a post on my blog about this. I discovered many other sellers fell in this blow in Brazil. Follow the link:

If you do not speak Portuguese, I'm afraid you will not have much interest in this post, now if you come to Brazil and think about buying / selling by LocalBitcoins, please use google translator to interact more about the subject And not fall into the blow.
What is the scam thought? The user reports you to the bank and he gets refunded? I cannot see how the other guy benefits from having your
account closed at your bank. I would recommend that you move to another bank... because they are totally clueless about Bitcoin. Your proof is
on the Blockchain and the receipt that you received via LocalBitcoin. Banks are just looking for an excuse to screw Bitcoin users.
