Here is eBay's announcement:

Due to recent policy violations, we are temporarily suspending all buying and selling activity for full bottles of beer and spirits listed in the Collectibles category. We expect to allow these listings again after developing and implementing additional, reasonable requirements to support seller compliance with our policies and applicable laws. We will continue to allow listings by pre-approved, licensed wine sellers.

We appreciate that the majority of sellers follow eBay policies regarding the sale of alcohol, and apologize to those who are being unduly affected by the violations of a few. We will refund all insertion fees and feature fees to sellers who have listings affected by this temporary suspension.
