Ah, sorry, I forgot to include the payment method. It was with PayPal. The buyer apparently used a PayPal account with a credit card that didn't belong to him/her. My friend's account ended up getting locked while it was investigated. The lock was released within 2 days, but the payment that was made by the buyer was removed from her account. I'm not sure of the overall outcome of the situation; whether she filed a report to lbc or not. I can check with her the next time I speak with her, but that's the gist of what happened based on her fb post regarding the matter.
That makes sense. If you use a reversible payment method to sell Bitcoin then you obviously open yourself up to be scammed whatever other precautions you take. Avoid Paypal and/or credit cards at all costs. I'm pretty confident using national bank transfers as my bank would have to agree to the charge being reversed with is very unlikely to happen.
