The TechTheft Bad Whois Blacklist is a domain-based blocklist that specifically targets domains with inaccurate or falsified WHOIS records. According to TechTheft, listings on this blacklist are semi-automatic and based on manually verified WHOIS information.

This blocklist is intended for informational use. Unlike many public blacklists, access is private and available only to subscribers by invitation. TechTheft's policy indicates that a listing means a network abuse complaint was received and has not been resolved. The blacklist (or blocklist) is designed to flag domains that lack transparent and accurate ownership information, which can be a sign of malicious activity.

The blacklist is operated by TechTheft, an organization dedicated to combating what it calls "Hi-Technology Theft", including spam, viral attacks, and DDoS attacks. The group advocates for a strong, proactive stance against internet abuse.

TechTheft's philosophy is that simply filtering abuse is not enough; it must be prevented at the source. The organization believes in cutting off services to all sources and supporters of such abuse, a policy they refer to as an "Internet Death Penalty". Their goal is to provide a collaborative point for administrators and others who wish to fight against technology abuse by identifying and blocking malicious actors.

The impact of being listed on the TechTheft Bad Whois Blacklist is generally low. Because it is a private list available only to a select group of subscribers, a listing will not cause the widespread email delivery issues associated with major public blacklists. However, if your recipients or their mail providers are subscribers to this list, you may experience email deliverability problems with them specifically.

Removal from this particular blocklist is directly tied to the reason for the listing: inaccurate WHOIS data. The official removal policy is to have the domain's status changed to "GOOD" or "UNKNOWN". Before this can happen, you should take several steps to resolve the underlying issues.

• Correct your WHOIS information. The most important step is to review and update your domain's WHOIS records to ensure they are completely accurate and not falsified or privacy-protected in a way that hides ownership.
• Establish an abuse contact. Ensure a functioning 'abuse@yourdomain.com' email address exists and that you are actively monitoring it for complaints.
• Resolve open complaints. If you are aware of any abuse complaints related to your domain, act on them quickly and ensure they are fully resolved.

There is no manual delisting form. Once you have corrected your WHOIS records and resolved any outstanding abuse issues, the semi-automatic system is designed to detect the change and remove the listing.
