Wasn't there a list of romance scammers out there? [View all]

I was checking on my SIL's address to send a xmas present and saw a listing of people who live at an her house. There was only her name but then I saw the name of a strange man I never heard of was, also, listed as living there a few months ago but seems to have moved back to his original address out of state.

I have lost touch with her over the last 6 months so I don't know what is going on. She is 88 and is a lonely widow -on the internet where she will be friend anyone.
I warned her about doing that so she de-friended ME!

Our nephew thinks this guy might be a scammer or an identity thief. He's going to call her to find out what's going on but in the meantime I was trying to find a list of romance scammers that existed back in the day but I can't find it any longer.

Thanks.
