Hoping it might help in the future others to report such ID10Ts, here's the ebay transcript. Apologies for the smilies abuse, for some reason can't get the editor to display the real characters, not even when I choose to remove formatting, unless I choose the code tags.

Hello, my name is Mark. Welcome to eBay Live Help. I can see that you were transferred from the other department. I am now checking your conversation. Please stay connected while I do this.
12:19:16 UTC Mark Nathaniel
Thanks for staying connected.
12:19:25 UTC Mark Nathaniel
I can see that you have a concern about reporting. Let me check this one for you.
12:22:26 UTC Mark Nathaniel
We're still checking on this. Please stay with me.
12:24:33 UTC Mark Nathaniel
I have checked here and was able to see that the account has no issues or any blocks related to reporting but no worries, I can surely have this report and I'll have this raised immediately.
12:24:46 UTC Mark Nathaniel
Can you please tell me the details about that item you are pertaining to?
12:25:59 UTC me
Thank you Mark. I'm trying to report a fake Seymour Duncan pickup ad. The seller has actually at least 2 items which are very ordinary forgeries.
12:26:35 UTC Mark Nathaniel
You're welcome. Thank you for providing these information, Adi.
12:26:38 UTC me
When I click Report I get the error I gave you above
12:27:00 UTC Mark Nathaniel
Do you have its item number so I can report it now along with your details?
12:27:55 UTC me
Sure Mark, there are 2 I'd like to report:
12:28:02 UTC me
eBay item number: 294093685547
12:28:19 UTC me
eBay item number: 254922449598
12:29:12 UTC me
Please keep in mind that other eBay users may have already reported at least one of them and at least another eBay user had his Report option blocked by eBay
12:29:19 UTC me
Just like in my case
12:29:55 UTC me
See this discussion on the Seymour Duncan forum:

12:30:50 UTC Mark Nathaniel
Thank you for providing these information, Adi.
12:31:06 UTC me
Not a good image at all for your business, looks like you're covering up for a seller advertising dodgy items. All considered, be great if you can look into:
12:31:19 UTC me
1. Restoring my ability to report items
12:31:56 UTC me
2. Take action and remove the fakes when you have received and investigated reports
12:32:58 UTC Mark Nathaniel
Yes of course and about your ability to report, I can certainly assure you that the account has no issues or any blocks that can affect your ability to report. Is this the first time that it happened?
12:33:09 UTC me
Many users have recently become fed up with the amount of fakes advertised on eBay, me included, it's kind of turned into the second alibaba / dhgate.
12:33:31 UTC me
Yes Mark, it's the first time it happens
12:33:35 UTC Mark Nathaniel
And for the items, no worries as this is already handled by our review team and placed with corrective actions.
12:33:43 UTC Mark Nathaniel
I see. Thanks for confirming.
12:33:57 UTC me
Let me try the Report again for item 254922449598
12:34:22 UTC Mark Nathaniel
It can be due to the browser used and a clearing of cache and cookies or logging out and logging back in might resolve it.
12:34:56 UTC me
There you go, tried "Report item" for 254922449598 and I got the same error: "We are not able to process your message now.Please contact eBay Customer Service."
12:36:14 UTC Mark Nathaniel
Thank you for trying and I'll have this checked further. I am now coordinating with my team.
12:37:20 UTC me
Ok, I've opened the item page in another browser (Firefox) and it appears I now get the "File a report" form displayed
12:37:32 UTC me
Previously I was using Palemoon, a Firefox clone
12:37:46 UTC me
Let me try now
12:38:09 UTC Mark Nathaniel
That can be the possible reason. The browser can also affect the website as it has its compatibility aspects.
12:38:18 UTC Mark Nathaniel
Yes, please.
12:40:45 UTC me
Right, so looks like using Firefox on my desktop I can use "Report item"
12:41:07 UTC Mark Nathaniel
By the way, I have already reported the items as well.
12:41:10 UTC Mark Nathaniel
Thanks for confirming.
12:41:19 UTC me
Think I managed to report both 294093685547 and 254922449598
12:41:39 UTC Mark Nathaniel
That's great. The report I made will also be expediting the process.
12:41:48 UTC me
Yep, all good, thanks heaps for your help mate

12:41:59 UTC Mark Nathaniel
Also, will act as a further proof so that our review team will be able to take further action on this.
12:42:13 UTC Mark Nathaniel
You're very much welcome.
12:42:47 UTC Mark Nathaniel
Thank you for contacting eBay Live Help. Goodbye, stay safe and take care.
