I too just made an account as I knew my unban should be happening right around now. My memory of my ban was it was only 10 years, and I never believed it to be permanent. I submitted a GDPR request that is pending and did the "inspect" trick that the was mentioned before my post. It's presumed I was banned on 2008-02-09 at 12:53:29pm. Which means if there's any hope that an auto unban will happen, my original 10 year assumption was incorrect as that would have already passed. If it was 4167 days as I'm hearing is most common, then I'll be checking again July, 8th of this year, but I'm not very hopeful. Just like many people here I'm frustrated that my account that I had spent a lot of money on in the past may never get returned to me despite it having a timed expiry date.
Sorry I didn't have much input, but I stand with you all with hope.
