We've banned this account as well as several others because they only post comments to defend Amazon against criticisms, and all the comments are more or less the same. That's not what this site is for.

You're welcome to participate on Hacker News if you want to submit stories and post comments about topics that gratify your intellectual curiosity. That is, you'd be welcome to participate as a true community member. But single-purpose accounts aren't allowed here, and certainly not single-purpose accounts for corporate agendas.
