Please help! A member here was mistakenly banned!

I'm a friend of another member here and his user name is "linksformer". He told me that he was informed by email that he was banned for giving fake itrader for this transaction:

But the fact is that he did buy this domain folkmk.com from the seller "newlungs", and newlungs also gave him an itrader for this transaction! Check here: http://forums.digitalpoint.com/itrader.php?u=339631

He also told me that he have been trying to contact the seller with no response, that's why he'd asked me for a favor to bring that up here see if there is any moderator who would kindly help him to clear this up, thanks a lot!

 

If mods have banned that person then there must be some reason..You need to prove about that transaction and also the person who was seling has to give some prove and confirmation.
