What is TechTheft Domain Blacklist?

The TechTheft Domain Blacklist is a semi-automatic, IP-based blocklist. Listings are added automatically from spam trap data and also incorporate domains featured on the spamsites.org list. This blacklist (or blocklist) focuses on identifying and blocking the infrastructure that supports spam and other malicious activities, not just the origin of spam emails.

According to its operators, this is a private list available only for internal use by trusted subscribers who receive access by invitation only. Its policy is to block IPs associated with spam supporters, which can sometimes result in collateral damage on densely populated hosts. This blacklist targets a wide range of abusive sources:

  • IP addresses of machines hosting domains owned by known spammers.
  • IPs of domains included on the spamsites.org list.
  • Domains selling software or services created for spammers.
  • Services offering 'bulletproof hosting' for malicious actors.
  • Virus-infected machines and web crawling agents.

Who runs TechTheft Domain Blacklist?

TechTheft describes itself as a collaborative effort by administrators and hobbyists dedicated to fighting "Hi-Technology Theft", which includes spam, viral attacks, and IP hijacking. The group's philosophy is to implement an "Internet Death Penalty" against all sources and supporters of internet abuse. They believe it is no longer sufficient to just filter abusive content; the source must be blocked entirely to prevent the abuse from happening in the first place.

How do I get removed and delisted from TechTheft Domain Blacklist?

Removal from the TechTheft Domain Blacklist is an automatic process. There is no manual delisting request form or contact. A listing is removed only when the underlying issue causing it has been resolved. The operators state that a listing will disappear when the "domain or spammer dies".

Before a listing can be removed, you must ensure you can receive and act on abuse complaints. You should set up an 'abuse@' email address for your domain and IP address ranges. The key to delisting is to resolve all open network abuse complaints associated with your IP. Once all active complaints are resolved, the IP address will be automatically removed from the blocklist.

What's the impact of being listed on TechTheft Domain Blacklist?

The impact of being on this specific blacklist is considered low. This is primarily because it is a private list used only by a select group of trusted subscribers. Therefore, being listed will not affect your email delivery to the entire internet, but it will likely cause your emails to be blocked by the specific networks and services that subscribe to this blacklist. For senders trying to reach those recipients, the impact could be a complete block of communication. The operators also note there is a risk of "some collateral damage on dense hosts", meaning legitimate senders sharing an IP with a bad actor could be affected.
