Update. Ebay replied to me this morning.

Ebay/

Hi Donald,

Thank you for contacting eBay back regarding your concern with searching
for items on the eBay site.

We do apologise for any inconvenience this may have caused you. We will
be escalating this matter to our site management pertaining to your
concern with numerous unwanted listings coming up in the search results
page. I will be forwarding a copy of this email to and a report to them
to have them investigate this issue.

While this matter is being looked into, may I kindly offer the use of
the Advanced search option as a remedy just for now that way you can
still make some searches for items on the eBay site without having to
look at a lot of irrelevant search results. Rest assured that this
matter will be looked into.

I'm glad I was able to give you the information needed to sort things
out.

Thank you for choosing eBay, we value your business.

Warm regards,

Roger M.
eBay Customer Support


Well, I have a not so patronising reply in mind. Stay tuned.
