There's no such thing as "real" or "fake" transaction, that I know off... if a transaction goes into the mempool, that is that is hows on these websites, it can only be on 2 states: confirmed and unconfirmed, that's all.
Your transaction may be stuck because of the congestion problem. Now that fee is $12 bucks at current prices and the mempool isn't that filled anymore. Should be enough to go through. I don't know why is it taking so long, but it's confusing since you said a fews ago, but the website shows this date: "Dec 27, 2017 at 04:40".
The reason you see it on that site only is because it never broadcasted on the network so the other explorers don't know your transaction exists yet.
