That's the day you created this account which then was used to complain in meta and continue posting in the speculation section, which is a bannable offense (ban evasion).
OP, if you did the above then you're screwed as far as your ban appeal goes.
Not surprising that your account was registered at the end of 2017, which is where
many spamming alt accounts were registered for entry into bounties and signature campaigns. I wasn't surprised in the least when I saw that. Now, I haven't looked at your post history and haven't investigated any alt accounts you might have, but it looks to me like you got caught copy/pasting--and every plagiarist I've seen on bitcointalk has initially denied doing anything wrong.
Unfortunately for you, it's a serious offense here since most members tend to get paid for their posts and plagiarism isn't tolerated by Theymos and the moderators. On another board you might get away with it. Here....not so much. But hey, I'll eat my hat if that isn't what the ban was for. 99.9% of them tend to be for passing off someone else's work as their own, however.
