Guys, who can tell how people involved in escrow find customers if they do not already have a track record? Do they first participate in simple transactions on the forum, receive positive feedback in this way and then offer deposit services?
Offering escrow without a track record
If you want to offer the escrow service, you must first prove you can be trusted by having a track record of successful transaction from previous trade. This doesn't mean if you want to offer escrow service you should go around forum participating in trade just to get positive trust (gain reputation) doing so might attract red tag.
Unacceptable behavior that will result in a red tag:
Lending or borrowing to gain "reputation"
When it says have good track record here's a possible guess,
You'd have to do other activities that would make you deemed trustworthy by someone. Then that person would approach you to act as an escrow for them. Then if you did a good job for them, they would recommend you to other people. After a while, you would have a good track record and have many to vouch for you. At that point, you can offer it yourself. That's my guess, at least. It kinda has to drop in your lap, at first.
Offering escrow service means you're officially announcing your availability to hold fund for large number of users therefore, if you don't have a positive track record for doing that for one or two users unofficially plus other previous successful trade records don't jump right into offering escrow service.
