Ok lets see now,
Newbie account - check
First post in the forum - check
No prior trust rating - check
No prior successful trade history - check
What could go wrong here?
Maybe post some pictures of the same? Not the stock images from the internet obviously, the ones that you have in store with you, with date and time.
This is a standard procedure, because a number of scammers are in this forum coming with newbie account and attempting to sell their devices while they actually have nothing to sell and it is scam.
