Is it like this one?
snip-
We're just the same mate I also encountered that, not once but twice.


At this time I know already that he was fooling me because I was almost being in a trap before in another account who has done the same strategy. If you know how scamming works, your trust judgment will naturally go out and you will avoid being scammed.
Scammers are anywhere. These type of modus are common. People who will be fooled by people like this is a newbie.
In that case, you have to trust the person if they have a strong background and reputation. Ask them openly about themselves to identify if they are scammers.
