Why are there no search suggestions on YouTube for the name "Peter"?

I've noticed a strange thing on youtube where it doesn't find any search suggestions for the name "Peter".

When typing the name, youtube queries this uri:

https://suggestqueries-clients6.youtube.com/complete/search?client=youtube&q=..

Normally there is a list of results returned in place of the empty array below:

```[ "peter", [], { "j": .., "k": .., "q": .. } ]```

I've tried on different vpns, different browsers, different devices, different internet connections, incognito, tor etc...

Is this unique for me and is just an example of how well they "fingerprint" users, or does everyone see this result?
