It happened to me too a couple of years ago, I am not 100% sure if it was from A4A (I think so) or another cruising app, but anyway from there (HOT pics!) we exchanged Nrs and started to chat on Whatsapp. At that time (I know, STUPID and naive of me!) I had my phone Nr connected to my FB page, so a few hours later this scammer sent me names and pics of family whom he would send our conversations screenshot to if I was not going to send him $1,000 within 2 hours...
After a moment of disbelief I replied that I didn't give a f*ck if he would send naked pics of me to my husband (who knows), sister, cousins and friends and that I would have notified the Police.
He disappeared and (as far as I know haha) nothing happened...
So, @roy7269, if I may advice you, don't be scared!
