But what if it's a totally new service, what would pull you over the line of trusting them/joining their site?
Most of the services here start from 0 reputations and even unknown person, it will be different if a company or big community offer their services.
How do they get the trust from customers or clients to work with?
- prove themselves trustworthy, there are several ways, but the easiest one is escrow, put their money in front.
- as time goes on, customer reviews will build their reputation, it's not in one night though.
