@pandaking , that small exchange who shall remain nameless, created their own market that's allowing users to trade Bancor IOU tokens. They aren't allowing you to deposit your BNT tokens.

Usually in most cases when an exchange makes an IOU token for an ICO/Crowdsale, they've bought into the original ICO and they are usually backing up each IOU share of the ICO on a 1 to 1 basis. The exchange didn't explicitly state what was backing up the IOU so that's another potential warning sign.
