Thanks, I may try that approach.
I suspect the issue is that the enforcement company is either using or abusing a known eBay process (depending on whether this is incompetence or done by design) to stop a listing. Given a credible reason to remove a listing, I doubt eBay have the inclination to investigate, so simply delete it, inform the seller and move on (with no easy way for the seller to appeal or re-list the item).
As was pointed out above, there are next to no listings in the UK for their cables.
