How to become trusted?

Hello I was browsing around and I saw some of the following:

There were SOP Trusted traders
-I was wondering, how (if you can) become trusted?

Middlemans
-What other transactions do they do besides paypal?

Sorry if previously answered questions / spam, first time here

That question has been already answered multiple times in this section. Feel free to browse around to or to ask questions.

It basically boils down to acquiring "trusted seller" status on SourceOP through many many seller trades involving cash.
As for middlemen, they aren't very much in use anymore.

A very very slim minority of users are trusted sellers or admins.

HI Mr Turtles,

Welcome to SR and yes it has been answered multiple times here. Aces summed it all up nicely!

As the SOP Trusted Seller List Manager we have very strict requirements for entry into our group. This involves a benchmark of 50 selling reps from 25 different members on the SourceOP forums among other prerequisites for applicant status. For full list of rules, see the link below:
