There was a UK planning department that got a lot of complaints, about them no longer approving any online applications for permits, and even the internal applications that were posted in and typed into the system. Mainly because every application referred to the erection of structures, which resulted in the email being silently deleted by the mail server.
Some years back, the visiting IT guy, as part of his ongoing campaign to destroy our system, somehow set the server "profanity filter" "to 11!".
I had to set an email to bloke in NSW whose name, if you squinched your eyes up, stood on your head, & farted, had a passing resemblance to the "F" word.
His details contained his "ABN" number, which the filter also had problems with.
The server rejected the email due to "racial vilification".
If you really stretched your imagination, & performed the aforesaid acrobatics, it looked vaguely like a nasty reference to Indigenous people.
Astounded, I sent the Boss an internal email, saying "The bloody thing rejected my email!"
That one was also rejected---------for profanity!
