I run a very small business. Occasionally I get emails from people whose first language is definitely NOT Englilsh asking to see my merchandise, as they have opportunities for me. They go to my spam filter.

A friend of mine's husband is an immigrant. He's lived in this country for more than 40 years, has a master's degree and is fluent in English, especially cusswords.
My friend, occasionally, gets messages, usually on her answering machine, claiming that her husband owes the IRS a lot of money, or there is a warrant for his arrest and if he doesn't pay them, things will get difficult. My friend is a legal secretary and knows this is BS. She has complained to various government agencies. They all say there is nothing they can do. But a scam like this is really despicable.
