I've never met a pet actually called "no-name" or "nameless". Two of my bettas don't have names because I'm horrible at thinking of names for fish, so they are nameless...but obviously, if I'm talking about them to someone I don't say "this is my betta Nameless"...I would say "this is my betta, he does't have a name" or something like that.


That being said, if someobdy wanted to name their pet "Nameless" or "No-name" I wouldn't care as the pet doesn't belong to me...
