chatting here for days or even weeks and then discover that the person you chat with is a scammer is pointless... I go straight on WhatsApp, video call problem solved, if they avoid that then bye bye
I actually had a video chat with someone, they were a crypto currency scammer, I am not sure they are all scammers but I treat them as such. They are still on Mingle now posing as 2 people with different names. So even a video chat doesn't solve everything.
