Let's wait and see, but that was totally unacceptable and irresponsible of him. He had the time and internet to apply and even spend the Bitcoins that were sent to him, but he then suddenly didn't have time to make a simple review even after several reminders?
Personally, I do not think that he would risk losing his account for the sake of this small amount, especially since this would not have cost him more than trying the site and publishing the review. Maybe he did not imagine that the situation would become so complicated, and most likely he was confused about what position he should take to remedy the issue, and this is explained by his direct contact with Royse without him coming here and providing any explanation to all who left him negative feedbacks.
By verifying a little in his trust history, it appears that he has precedents for delay in payment, and he actually has an active loan in the amount of $ 40 Bitcoin since years ago from DS, which he has not repaid until today. I think that explains his bad habit.
