Should also go back and check to see if you were unbanned. I was banned during the API purge, for mass editing+deleting my comments. First automod banned me from various pro-Spez subs when I started editing my old comments. Then when I repeated the edit+delete with my second/third/etc accounts, it banned them site wide for ban evasion.
Went back a little while later, and all of my accounts were magically unbanned and all of the edits+deletes were undone. The benign explanation is likely that the ban(s) prevented any of the edits from actually committing. But the more tinfoil-hat explanation is that the admins want the site to look more active, so they rolled back bans so old content was still available and their user count appeared higher than reality.
I think it’s a joke about physicists not understanding tolerances.
I remember hearing an old story about a company buying signs from a contractor. The contractor produced all kinds of things, so it was fairly straightforward to send them the CAD file and stop worrying about it. One manager did an audit, and realized they were paying hundreds of dollars each for these basic signs. They weren’t fancy or anything, and were just signs throughout the facility that got updated regularly. So why the hell were they paying so much for what should have been a simple print job?
After some investigating, the manager discovered it was because the engineer who did the original design for the signs forgot to change their default tolerances from 3/1000 of an inch. The contractor was busting out calipers and meticulously measuring the spacing and sizing on each letter before it shipped out the door.
