Thanks man
I have already experience with this kind of stuff. I analyzed fake accounts in a other forum/community before i came here.
I watch at details which most users not see at the first view.

And there are a lot more accounts which show this structure of post history! Not only the few examples from my post above.
Unfortunately i can't research them all, i have not enough time and money to do this. And the admins have a better resources/tools than me. They can check IP addresses to compare accounts and posts. This way they can see if they are all produced by the same "farmer".
My first impression is, they are all from the same!

I think, the time will show how interested the administration is to do something against this farming. If they do nothing, then the accounts could be made by the admins also! As a way to profit from the forum. And who knows, who is QS? It could be possible that this is a second identity or private account of a Admin.

You know, we have a guy who made trust ratings for all the coin devs. But is there also a guy who test the most popular accounts here? Such as admins, sellers, escrows of this forum... The trust feedback of the forum is easy to manipulate, a second opinion would be the best!
 
But for now, lets wait and watch how much effort the administration shows to support the own rules. Because i think, i read somewhere "account farming is not allowed".
And if the administration should need some kind of help to research this, I wouldn't say no...
