I THINK I found a HIGHLY possible reason as to why I was banned.
I logged onto the e-mail account of the amazon account I closed myself about a year ago and sent a message to this "amazon specialist" if they could reopen the account.
Here is the process you need to follow when closing an account: http://www.amazon.com/gp/help/custom...?nodeId=565164
I followed this step back in 2011, and got a confirmation from a regular customer service agent that my account was closed.
However, after e-mailing the account specialist, I got the same e-mail that this account was linked to an account with previous abuse. WTF? I think closing the account by myself flagged my account as closed by amazon, thus by abuse.
