Yes, I accept that. I'm personally lucky that all the people alive with my surname in the world are related at the great-grandparent level. There's less than a handful with my firstname.

I briefly looked into trademarking my personal name (legal to do in Australia) but its cost prohibitive (vs verifying for multiple online platforms).

I even thought briefly about legally changing my name to include a new middle-name that was my PGP short key id. But Australia does not permit the use of numeric symbols in names. (Though I guess you could shift the hex string by 10 so 0-F maps to A-P. That wouldn't break the rules.)
