They are all connected ... all of these trade posts lately are just a theater-play, shifting little amounts, trust-farming etc.
They are all the same, another example

And so on ... not even Flash would be able to do trades so past (starting with the first post).
... minostel, coinman, moritz30 and whatever ... anyway, wont stop them much. Im sure they create more accounts than burn same time.
If you have further suspects please feel free to PM me. I will sure give them a shot in looking at their history to check if they are related or had any alts from which they had earlier scammed someone.
