Another case of fraud implicated me, but was against another member. Someone hacked into my account and posted a listing of a four channel Mcintosh amplifier for sale for $1920 with the scammer's PayPal address for payment. Fortunately, I received an email in time from Audiogon, "my item had been sold" along with the details. I emailed the buyer, told him I had nothing for sale, the ad was a scam - DO NOT PAY. Fortunately, he had not paid yet, (there was a message from the scammer saying it was past midnight and the buyer should pay right away so he could ship it out that day).
I have since changed my password and corrected the data on my account and no harm was done.
Here's a thought:
If you buy something on Audiogon, don't pay right away just in case it is not 100% legit - you might save yourself a lot of grief.
