It seems like there is a lot of information to hide so you will only be told via PM and you decide if it's something your comfortable in doing, that is why I also want to find out what kind of business it is before I consider doing it.
Well, If it is something to hide in the first place there is surely another aim for this project and i supposed it is not a positive one. Plus anyone that try to make a good business try to at least share the abstract of the proposed project.
It gets suspicious when you don't share the products you are selling, digital products or not. In fact the OP is using a bad marketing idea since here because if he talks freely here the request to cooperate with him will be much higher if he is selling legal digital goods. If he wants US, UK and Australia accounts to sell I am guessing that the OP wants to sell Windows Keys or COA stickers throughout this accounts and make really huge profit. I don't know if this is legal to do but thats just where my mind goes.
This is far from what you currently think you don't even know the project yet and i doubt that this is all about selling a digital goods because it could easily be done in the auction or on the goods section itself.
