Assuming that they don't dox themselves some examples that would trigger a filter:
- Phillip K. Dick, etc., So like a body part or cuss word, or even an ethnic slur, for instance in Papua New Guinea a hundred or so people have the surname “Wop” which might trigger an algorithm. “Fokker” is a Dutch example of this, refers to someone who was an expert in getting animals to breed—possibly some other culture has a variant like Fucker that's the same.
- The name could be identical to a celebrity, for instance a Malcolm X born to Arthur and Jenny X having nothing to do with the more famous person of that name. Then you would still say “it’s because of my surname.” Alternatively the celebrity could be notorious e.g. if your name were “Jack Hittler.”
- The James Randi Educational Foundation once dismissed an application for a prize that they administer, because the person did not appear to be using their real name. This had to be reopened when notarized copies of a court order changing the name were submitted, confirming that he had indeed changed his first name to Prophet and his surname to Yahweh. So if that guy has kids with more normal first names...
