TechTheft Support Blacklist
The TechTheft Support blacklist is a blocklist for IPs with unresolved abuse complaints, removing entries automatically once issues are fixed.
Updated on 17 Jun 2026: We updated this guide to clarify that TechTheft Support Blacklist concerns spam-support infrastructure, not consumer tech support scam lists, and added a clearer delisting workflow.

The TechTheft Support Blacklist is a private, IP-based blacklist (or blocklist) for infrastructure associated with spam support. Its listings have been described as semi-automatic, based on spam trap data and domain evidence associated with spam-support activity. The policy is to identify infrastructure that supports spamming operations, so system administrators can block or boycott those services. Some collateral damage can occur on dense hosting networks because a shared provider can host both abusive and legitimate customers.
Despite the similar wording, this is not a consumer tech support scam blacklist for phone numbers, pop-ups, or fake support websites. It is an email and network abuse blocklist focused on mail, DNS, and hosting infrastructure.
This blacklist (or blocklist) specifically contains:
- The IP addresses of mail servers (MX) that handle email for spammer domains.
- The IP addresses of name servers (DNS) that provide resolution for spammer domains.
- Networks and Internet Service Providers (ISPs) that refuse to terminate spam services.
- Networks and ISPs that do not respond to abuse reports. A quick resolution to a problem is considered a valid response.
Who runs the TechTheft Support Blacklist?
The TechTheft Support Blacklist is managed by the TechTheft organization. The group's stated focus is fighting what it calls "Hi-Technology Theft," including spam email, viral attacks, Distributed Denial of Service (DDoS) attacks, and the hijacking of PCs and IP addresses.
TechTheft's policy position is that filtering abuse after delivery is not enough. It has advocated an "Internet Death Penalty" for sources and supporters of malicious activity, meaning communication from listed infrastructure should be blocked at the source instead of only filtered after acceptance.
How do I get delisted from the TechTheft Support Blacklist?
Removal from the TechTheft Support Blacklist is automatic. There is no public manual delisting form or request page. Your IP address is removed from the blocklist only when the underlying problem that caused the listing is fixed and the abusive service is no longer active.
Before waiting for automatic delisting, check the systems that can make an IP look like spam-support infrastructure:
- Confirm the listed IP is not accepting mail for known spammer domains through its MX records.
- Confirm the listed IP is not providing DNS resolution for domains tied to spam complaints.
- Review abuse complaints for the customer, server, or network range and close the active issue rather than only requesting removal.
- Keep a working abuse@ mailbox for the domain or provider and respond promptly to future complaints.
If you see a DNSBL response in the 127.0.1.* range, it indicates that the issue has been discussed publicly in Usenet groups. Search historical newsgroup archives, including news.admin.net-abuse, to find details about the complaint and the affected infrastructure.
What is the impact of a TechTheft Support Blacklist listing?
The direct impact of being listed on the TechTheft Support Blacklist is usually low because it is a private blacklist and is not available for broad public use. Subscriptions are by invitation only to organizations that TechTheft trusts.
Your email deliverability is affected only when sending to a mail server operated by one of those private subscribers. Even so, a listing on any blocklist or blacklist is a reason to investigate abuse complaints, unauthorized customer activity, compromised servers, DNS delegation, and provider response processes. The listed IP can point to a real operational issue even when the list itself has limited reach.
