After some activity here at Codex, I submitted a frozen a ticket after reading a thread regarding a change in Neopets ownership. To my surprise, today I found myself unfrozen! I received a response within one day of submitting the ticket and after some back and forth they decided on unfreezing my account. Coming up on 10 years since it's been frozen.
Great nostalgia! If you're reading this and you have an old frozen account that hasn't been purged, go for it!! Submit a ticket. To verify your account is still in the database you can check /~pet pages and user/pet lookup pages. Good luck, any questions with sensitive information feel free to email me
