My mom got caught up in a romance scam off of some sort of Christian dating site & was out some money because she bought the guy a couple of iPads and shipped them to him. My mom is a bit of an idiot though, so there's that. When we realized what had happened, after Mr Romance didn't show up at the airport here, to meet her as planned, we tried helping her - my brother took her computer and worked it over, we reported to the police, etc etc etc. She was more mad at us than she was at the scammer, and accepted a couple of phone calls from him afterward, with him screaming at her. It was an utter gong show. But, not my problem anymore, we don't speak and haven't in almost 10 years (lots of backstory here involving immense amounts of abuse).
My mother-in-law sometimes answers & she just starts talking in Plautdietch and they hang up in a hurry and almost never call back.
They have been caught out once & had to replace a credit card, so they tend to call us about stuff now, if they're ever tempted to look into things further.
