A type of scam involving feigning romantic intentions towards a victim, gaining their affection, and then using that goodwill to commit fraud. This may involve access to the victim’s money, bank accounts, credit cards, passports, email accounts, or national identification numbers or forcing the victims to commit financial fraud on their behalf. Often called dating and romance scams.
