Thank you I appreciate you saying this.  Can you post what value you have YAAMP_FEES_EXCHANGE set to in your config?  Or better yet any of the relevant fees settings in the server config?  Perhaps there is a setting that should be .2 instead of 2 and that's causing the normal 2% to be 20%.

I'm looking over the Yiimp code and trying to determine if it is in fact a bug or some config that is set incorrectly.

As I mentioned before I don't think that anyone would protest to paying some fees for autoexchange as long as they were stated up front so someone could decide if the fee is worth the trouble or not.
