erase confidential data from the GMANE repository

Hi;

since 2 days i try to contact someone from GMANE who could erase an article with
confidental information, which has been unintentionally published. I have
already explained my issue in full detail to the following email adresses:

larsi+suppress <at> gnus.org
larsi+gmane <at> gnus.org

The original source of the article has been erased by now. I also followed all
advices on the GMANE-FAQ. 

Can any GMANE administrator please take a look at the email accounts i mentioned
above and tell me how to proceed ?

thanks,
Hussayn
