psyciceman: Well if you know how to con yourself, wouldn't that make you harder to con (in theory). But trusting your gut tends to (at least in my case) be the right thing, sadly I only learnt to listen to my gut recently, but oh well.
craig_ethan_123: What does this person do specifically?
I could have bet money that you'd respond to this :)
The person who constantly scams people on GOG is obviously young, arrogant and far less intelligent than they think. That is their downfall versus someone experienced with bullshit artists. I'm not saying that I know it all but there are plenty of "tells". Face to face someone doesn't stand a chance vs someone who can read body language well and knows how to trick the con-artist into a false sense of security - micro-expressions don't lie. A good understanding of language and communication does wonders for being able to read between the lines.
The social engineer enjoys this game. They want to be recognised. Anyway, enough on that or I'll give away all the detective secrets :P
