but worth noting in case anyone else experiences this. Some time after the events last night I went to list a couple more items. When I hit the 'list' button I got a dialog box with the message shown at the bottom below and a link to send a message to ebay which I did. I subsequently called them to check it was genuine and confirmed it was, but they would not indicate which item had triggered it. I listed a whole range of different items yesterday.
I got an email reply a short while ago:

Dear David,

Thank you for writing eBay in regard to the recent restrictions you've
experienced on your account.

In order to maintain a safe trading environment, selling limits are
occasionally placed on accounts. A restriction was placed on your
account to limit you from selling or revising certain items. The
restriction will remain active at this time.

Please keep in mind that you are not permitted to sell items on eBay
bearing the name or logo of a company if the product has not been made
or authorized by that company. In addition, the sale of counterfeit
items, unauthorized replicas and unauthorized copies is prohibited by
law, and therefore cannot be listed on eBay. It is the seller's
responsibility to ensure that the items you are listing are authorized
for sale.

This policy also helps protect buyers from purchasing counterfeit or
fraudulent items and helps protect the intellectual property rights of
third parties.

As always, our goal is to keep the eBay marketplace a safe place to buy
and sell. Under our User Agreement, we may remove listings if they
breach one of our stated policies. Further, we may warn or suspend
sellers whose activities breach our policies.

I encourage you to read the information available on our Help pages
about why we may remove items from the eBay site.

http://pages.ebay.com/help/policies/replica-counterfeit.html

Please understand the restrictions placed on your account are not
accusations of you personally selling counterfeit items nor do they
affect your standing as a valued eBay customer. The restrictions are
proactive means of assisting eBay to reduce fraud and negative buying
experiences on the site.

Thank you for your time.

Sincerely,
Kaley

eBay Customer Support

Message: Upon trying to list, I received a dialog message-
"In order to maintain a safe trading environment, selling limits are
occasionally placed on accounts listing items that are reportedly
favored by counterfeiters. At this time, you are limited in the number
of items you can list (or revise) in any 7 day period. If you have any
additional questions about this subject, email us at Customer Support."

Perhaps someone could explain exactly what this about?
