Once I had a problem with one Neteller trader, and he asked my passport or ID for verification and I didn't give him as I don't trust anyone with my personal docs.
Later we didn't make any trade, but the trader left a negative rating on my profile saying that I didn't provide ID for verification.
Why do buyers need to provide personal docs to some unknown person while the buyers who already have a verified account on LBC? In my opinion it's totally unnecessary and I think LBC need to put some changes on their terms.
Were you the one to who were supposed to pay him via Neteller? If so, he didn't want to risk dealing with the risk of accepting a payment from someone with a hacked or stolen account. Verified LBC accounts can also be hacked or sold.
