What is really interesting is that while both Tradehill and Mt Gox heavily used Dwolla, Tradehill seems to have had more problems with it. Tradehill reports $100 000 charged back. Mt Gox reports 5000. Tradehill reports that Dwolla would try to charge stuff back in a hidden manner by changing the status of transactions after the fact without notifying them of the chargebacks. Tradehill further reports that Dwolla would completely ignore them and stone wall them when they tried to discuss the matter. Mt Gox on the other hand reports that Dwolla were very good about reporting the chargebacks and there were no communication problems.
Now for those of you that do not know: Mt Gox is the leading bitcoin exchange that does most of the business. Tradehill was an upstart that tried to compete with Mt Gox and even when active only did a small portion of the business Mt Gox did. Furthermore, Mt Gox does so much business that they were reporterdly Dwolla's top client for a while and that may still be the case.
Please feel free to provide your own speculations as to what all of this means.
I can tell you why Mt Gox has fewer problems with Dwolla than TradeHill. MtGox goes to incredible lengths to keep the bad guys away from their exchange: they forbid web sessions coming from TOR, they ask for proof of ID for users handling the most money (over $1k/day or $10k/month), they track stolen bitcoins and freeze Bitcoin deposits made to them containing known-tainted coins, etc.
As a consequence, the bad guys tend to operate on the less protected exchanges, such as TradeHill, and they get hit by Dwolla's chargebacks, coming mostly from hijacked/fraudulent Dwolla accounts...
MtGox's report of $5000 of Dwolla chargebacks is so small it could very much have been only 1 or 2 incidents. Of course Dwolla is going to have much more time communicating with their largest customer about 1 or 2 incidents, than investigating possibly hundreds of fraud cases involving a customer like TradeHill representing a small fraction of their business...
