These people buy newly expired domains and try to scam money out of you. They'll mail you a letter saying your domain is expiring and try to get you to pay them crazy money to renew it. Don't do it! They try to mislead you by making the letter look official but they're just trying to scam you money.
Then they'll e-mail you to renew your domain for 6x the normal price. Scummy business practice.
