Member posting same request over and over again

[Emmy]

There's a Danish member who on May 29th posted an (incomplete) request to add two books here:
https://www.goodreads.com/topic/show/...
to which we replied pointing out to the guidelines and the 'one request per topic only' recommendation.

Since then he resubmitted the very same request almost twice a day, most of these were closed as duplicates, but on June 5th I was fed up with it and flagged the new request here:
https://www.goodreads.com/topic/show/...

But still this member stubbornly keeps submitting the same request over and over again, now even with the topic title in allcaps:
https://www.goodreads.com/topic/show/...

What else can be done besides flagging these duplicate requests? It feels like trolling... :-(

Jaclyn will see this post when she is looking at this later and will likely address it at that time.
In the meantime I would stop responding. It's not worth our time and effort,
EDIT: especially yours as you have been more than fair and helpful to everyone.

Have replied to those threads - let me know if you see any more reposts.
