Well there is no final proof and will never be, but on telegram channels some "bots" who received payments have replied to some questions on how they completed the verification. But again I think for bigger accounts the story will be different. They will ask our mum in hostage before sending money.
If they are really repaying, then they can start repaying some of the bitcointalk.org members and I'm sure that I'm not the only one here. Until now, I didn't get even a bot reply for further instructions, so I can assume that this is another bs confirmation of getting funds back from them.
I'm a real person. I received the payment. It took a while, but I received it. Most people are posting one liners probably because English isn't their native language and they are just copying and pasting to be compliant with the Livecoin instructions to receive the other half.
