When my daughter was in High School, there was a math teacher who was almost universally disliked for her superior attitude. This teacher’s first name was Trudy, but when the school paper ran an article about her, it came out as Turdy.
Most of the students had a good laugh, but the teacher ripped the journalism advisor up one side and down the other, and refused to be convinced that it was a typo.
My old company (very, very, very large and privately-held) did an almost entirely hands-off, ridiculously poorly-planned rollout of Microsoft’s SharePoint.
In the Wild West info anarchy that ensued (surprise!) someone loaded a Human Resources spreadsheet into the system and forgot to mark it as private. This was discovered when someone else ran a search using “confidential” as the keyword, and up popped the spreadsheet which contained, among other things: pay level, home address and social security number.
The person who loaded the spreadsheet was fired. Nothing else was done differently.
My HS newspaper once had an article on how well the school’s “Breakfast with Satan” event was. Someone used the Find/replace function on the paper after the Principal had vetted the paper before it was sent to the printers.
