No kidding, just like how every order on newegg of mine will always be cancelled

I've been seeing abuse reports from Sony lately, indicating IPs are blacklisted on the Playstation Network, mainly for attempted account compromise.
Indicating to check for traffic towards some endpoints, resolve the complaint else blacklist again, etc, etc. The address they direct inquiries to is snei-noc-abuse@am.sony.com - perhaps this is a reason and vector for your issue as well?
