From 2007: Various sources and my own investigation show that the website seems to be running on autopilot with nobody at the helm.
A postmaster at a large ISP contacted me and indicated that he had received no response to DNSBL remove requests submitted to TQM. Those requests were submitted on March 27th, and it is now June 30th (2007) that I write this article.
Other data points showing that the list appears to be unmanned and likely abandoned:
The list's website has a "last update" date of March 11, 2007.
The last known response received in reply to a blocking list remove request seems to have been in February, 2007.
I contacted David Cary Hart via email to the address on his domain registration on June 20th, 2007, and have not received a reply.
I contacted the abuse desk of his ISP (Fortress ITX) and asked them to confirm that he was alive. This was on June 24th. I received a ticket number but no other response.
The DNSBL's experimental world zone has not been operational since December, 2006.
The last known sighting of Mr. Hart online appears to be here, from April 2007.
This newsgroup posting from Colin Leroy on June 14, 2007 indicates that Colin had last seen email from Mr. Hart back in December, 2006. The email was a message posted to a mailing list that they both participate in.
- Others have indicated to me that they have called the telephone number in the TQMCUBE domain registration, and that the voice mail box associated with this phone number is full, no longer accepting new messages.
This thread in the news.admin.net-abuse.email newsgroup wondering why the list's administrators are non-responsive is typical of the discussion I've come across during my investigation. I am receiving numerous reports of issues with listings going unresolved. Additionally, when checked against my personal spamtrap data (8000+ spams/day) I am seeing the effectiveness of this list trending downward over the past few weeks.
After careful consideration of all of the facts and discussion surrounding the status of TQM and its maintainer, I do not think it is wise to use the TQMCUBE DNSBL.
November 25, 2007 update: Within the past week, a large number of entries have been removed from the TQMCUBE blocking list database. The Internet Wayback Machine suggests that TQMCUBE had 1.37 million IP addresses listed on August 29, 2007. As of today, November 25th, the TQMCUBE website suggests that there are approximately 851,000 active listings.
