I remember matching with really hot, model looking Asian girls on some apps that were quite frankly out of my league. They would message me and say they recently moved to the US for work or something. Never really got beyond the initial greetings as they were super dull to talk to and I started finding it fishy that I was getting multiple matches like this with the same type of profile. Pretty sure those were all pig butcher scam attempts.
I of course stopped liking those profiles and for a while Facebook Dating in particular was infested with them.
