Ok, something very strange is afoot. I decided to check the notification emails, to see exactly when my username got capitalized. The conclusion, as shown by the screenshot shown below is: that my username has been capitalized for months. However, I am very sure that it has not been capitalized at least since Ookla season, and that I have not changed my username since then, but it wasn’t capitalized yesterday.... Either Mandela Effect Shenanigans, or Time Traveling Shenanigans. Possibly both.
