That reminds me of my Linux server teacher in university. We were to buy a domain name from Namecheap or Gandi during class with some free credits, and the teacher was recommending lastname[dot]com if that was available.
I happened to say aloud “yep, mylastname[dot]com is available” and he quickly sushed me as if I had named Voldemort aloud in Hogwarts, telling me that saying it is a really bad move… lol
