gokano.com:is it a scam or it's legit?

Hello guys,today I choosed to talk about gokano.com,the give-away website that is making a reputation since 2015,I've been a member of it and I've had an experience that no body have done with it.
​I wanted to share with you a small review about it.

So,as I told you,I was a popular member of this website as I had more refferals than every member did and was getting 2GN for every refferal(GN=points that you redeem for prizes),so I wasn't giving importance to this points even if I had a chance to redeem them for expensive prizes like iphone 6 or a Motorola smartwatch.
What I did is being in a contest they organized,and I won by creating a video about their wesbite and getting the most views,I got 27000 views and other members were only having 120,200,500

views in the top of them,So they told me you won a go pro,I was happy and I told all my family(what stupid I am,now they forgot thank god) they asked me for my adress,I gave them my adress.
I waited for 1 month,2 months,then I became supicious I sent them a message on their facebook page they did not respond and there was a surprise:They also closed my account,I started spamming their facebook page and no answer were provided.
So guys,this is a wise advice don't play with them,they are scammers,even if you see prizes proofs on their facebook page,yeah they are giving awards but only to few peoples so that they get the most of the others.
Another point,how are they making money?
Really easy,they are getting millions of people surfing their website each day and watching the ads even without clicks and also they have the tasks and survey panel that they are geeting paid for.
