If you’ve been targeted once, you’re likely to be targeted again.
If a scam artist receives money from you, they will often hold onto your contact information for future use or sell their list of names and contact information to other scam artists for profit. After some time has passed, you’re contacted by the first scam artist or a new one. They tell you that some or all your original investment has been lost and claim that they can help recover your lost money for a "fee." However, if you pay the fee, you’ll lose that money, too.
