Basically, no two thoroughbreds can be registered with the same name. Basically the same issue.

At first I thought "if people can come up with unique WiFi hotspot names how hard could it be to come up with a unique horse name" but then I remembered I've basically seen the same five wifi hotspot jokes repeated ad nauseum over the years.

Now I'm wondering if there's been a racehorse called "FBI Surveillance Van".

I guess I just don't see why that would cause the names to be "Insane". Random pet first name + owner's last name/sire's name seems fine.
