Absolutely agree with the other 2 before me. It would definently add to my security when buying but I wouldn't buy if that was the sole authentication on the jersey. I'd want some other proof because Twitter isn't fool proof. You can set up an account for anyone. I'm NOT saying you did that whatsoever and I'd love to think no one would do that!!! But let's be honest that's what we deal with being in this hobby......that there's scumbags who will do anything to make a buck.
