Yes, I was the one who supposed to pay via Neteller in return of BTC.

Thanks for the point!
Yes, this could be a reason for asking the personal docs, but still how can we trust a stranger with our personal docs? Those traders later may use our docs for an illegal activity...

What I was trying to say earlier in my post, that LBC should do something for all buyers & sellers so that there is no need for extra ID verification. If a solution introduced then both the buyer & seller will be safe imo.

After that incident, both the seller and I (buyer) had to stop trading in LBC due to the poor rating on our profiles. But both of us hadn't traded nor we scammed each other, still left a negative rating in both of the profiles.
