Scammers are very adept at knowing how to "play" their victims - sending love poems, sex games in emails, building up a "loving relationship" with many promises of "one day we will be married".
The scammer will offer to fly to the victim's country to prove that they are a real person. However, when the victim goes to meet the scammer they never show up.
They tell their victims that they are lonely, supporting an orphanage with their own money, needing financial assistance because they can't access their own money in a combat zone, etc.
The money is always sent to a third party to be collected for the scammer.
A romance scam is a confidence trick involving feigned romantic intentions towards a victim, gaining their affection, and then using that goodwill to commit fraud.
Fraudulent acts may involve access to the victims' money, bank accounts, credit cards, passports, e-mail accounts, or national identification numbers or by getting the victims to commit financial fraud on their behalf.
