I had this happen to me … in my case, it was a person who asked my half-sister and an acquaintance to send money to “me” in London, as “I” had been mugged. Neither had any idea that I was in London but thought it was plausible, as my husband’s family is English. Luckily, the person had atrocious spelling and grammar, which gave it away!
I’ve since changed my password to one containing letters, numbers and symbols and had no further trouble.
