Re: Sharon T. Pokeworthy...
Someone once performed some tests on the US Army's personnel database, and in that occasion entered a "Private (E1) Donald Duck. After a couple months, they found this fake record had been updated. Among other events, Donald Duck had been promoted to Private First Class (E3), transferred to a different base and was having pay deposited to a real bank account.
Fearing fraud, the IT guys called the base in question and demanded an explanation. After some confusion, they got it. There really was a soldier by the name Donald Duck, so of course the Army paid him.
They decided in the future to do their testing with names like "AAA X. QQQQQ". Even with US naming habits, that should be safe for a while.
