well, i have this guy jon.viruete on skype and he says is a so called escrow..
why would i receive neg trust just for offering a guy?
so i need to be an expert on all the users on the forum to not receive neg trust?
No, you just need to use your common sense. You realize it seems like you're and alt of johnmatrix or at least colluding with him, right?
At the very least you lack basic judgement to make safe deals so a warning is necessary. You should always deal using a very trustworthy escrow for everyone's safety.
