The TechTheft Blacklist is a private, comprehensive IP-based blocklist that combines multiple zones to list sources of network abuse, with delisting from this blacklist only occurring after all open complaints have been resolved.
The TechTheft Blacklist (bl.techtheft.info) is a private IP-based blocklist used internally by its subscribers. It's a composite blacklist, meaning it combines all of the IP addresses listed in its various sub-zones into a single comprehensive list. The operators caution that using this main combined zone carries a high risk of collateral damage, or blocking legitimate email, and suggest that users consider using the individual sub-zones instead if they are concerned.
According to TechTheft, their traps list any internet asset they come into contact with, which includes:
This blocklist is private and not available for public use. Access is granted by invitation only to trusted parties.
The blacklist is run by an organization called TechTheft. Their mission is to combat what they term "Hi-Technology Theft," which includes spam, viral attacks, and Distributed Denial of Service (DDoS) attacks. They provide a collaboration point for administrators and hobbyists who want to fight against technology abuse.
TechTheft advocates for a very aggressive approach, calling for an "Internet Death Penalty" against all sources and supporters of internet abuse. Their policy is to block not just the offending IP but also its supporting infrastructure, such as DNS, mail hosts, and web hosts. This philosophy stems from a belief that earlier anti-spam systems like MAPS and SPEWS were ultimately too slow or lenient to be effective against modern threats.
The delisting process for this blacklist is based on resolving abuse complaints. An IP is listed because an abuse-related complaint was sent and has not been resolved. Once all active complaints associated with your IP address are fixed, the listing will be automatically removed.
Before requesting delisting, you must ensure you have a working abuse contact. TechTheft specifies the following:
TechTheft states that you can find a list of open complaints related to your IP on their site, which is the first step to resolving the issues. They do not provide a public delisting form; removal is contingent on fixing the underlying problems that led to the abuse reports.
The impact of being on the TechTheft blacklist is generally considered low. Because this is a private list available only to subscribers via invitation, its adoption is not widespread. Unlike major public blocklists (or blacklists) that are used by thousands of mail servers, a listing here will only affect your email delivery to the specific, limited group of networks that subscribe to it.
