From one of the comments in the article:

To avoid future denials of service that public blocklists can apparently cause, we will no longer use them as part of our anti-spam regime.

As soon as I heard of the ordb.org rearise I suspected that spammers might actually have restarted the ordb.org service with these errornous behaviour. There is no faster way to get people to loose trust in the public blocklist services than one day of blocking of all legitimate emails.
