What happened:
So the user btcbounty made a thread on the service section about buying referrals under his Gokano account for 0.002 BTC each and so some forum members signed up under him including me and he promised to pay and he did pay only to the first few members signing up under him and for some of us , there was the problem of Malleability attack going on so the amount he sent got labeled doubled spend on the blockchain so as result I pm'ed him as said : The transaction just got double spend as you may see in the picture: ( You should ask the blockchain support as lately many double spend transactions happening since last night )

his answer to that pm of me is the one on Oct,5 and until now nothing has happened

His two last posts on the thread:

Can someone on Default trust give this account negative rating ?,
definitely lying. according to the address he sent the payment from , btcbounty is the same person with escrowboy, while escrowboy is offering loan in this thread

6) In the 2nd screenshot I posted , you could see on one of his replies that his asking for a feedback
7) If anyone could give his four accounts a lesson it would be very helpful as clearly his a scammer and it would be better to not do any business with any of his accounts

Updates:

Update 1: Found another two of his alt accounts: wayayo and Shield
Update 2: Shield is Pending to be removed as the text was miss-red but due to some feedbacks associating it to the list, I'm waiting for some proofs
Update 3: Shield is not an alt of the associated accounts , apology on my behalf for mistakenly put your name on this thread and sorry for shorena that I provided wrong info here
Update 4: User has now payed all the remaining payments with another address of him: https://blockchain.info/address/16fYvWaM7USgE1pHKqdK5t9CZXCiRoiic6
