[anti-abuse-wg] Whois database accuracy

Hello,


I use to report spam to the spam abuse mailboxes which are defined by 
the whois database.

However, I'm always encountering the below issues:
- the mailbox domain isn't valid
- the mailbox is full
- the mailbox doesn't exist


Who can I contact in order to ensure the Whois database is tidied up.

I tried to reach the top registry of the domain (-l whois option).

However nobody is fixing those reference databases !

Could we possibly disconnect the network which aren't tidying their 
whois records ?


Regards.
