What is Domain Blacklist Check?
Simply put, it's checking whether a domain has been listed on various “bad” lists by network service providers and security agencies before purchasing or using it. This list is like a domain's “credit record,” documenting whether it has been used for spam, malware distribution, phishing, or other inappropriate activities in the past. If a domain has such “black history,” it's likely to be blacklisted.
Potential Problems if Domain is Blacklisted
Impact on Website Traffic
When a domain is marked as unsafe by browsers or search engines (like Google, Bing), users will see warning pages when visiting your website. This greatly reduces user trust and causes your website's ranking to drop in search results, or even be removed entirely.
Impact on Advertising
Most advertising platforms (like Google Ads, Facebook Ads) check domain reputation. If your domain is on a blacklist, your ads may not pass review, or even lead to your advertising account being banned.
Impact on Email Sending
If your domain is on an email blacklist, emails you send (like order confirmations, marketing emails) may be directly blocked or automatically categorized into spam folders, preventing customers from receiving important information.
Why Domains Get Blacklisted
Sending Spam
This is the most common reason. If a domain is used to send large amounts of unsolicited advertisements, scam emails, or false information, email service providers (like Gmail, Outlook) will mark it as a spam source and add it to blacklists.
Spreading Malware and Viruses
If a domain is used to host malicious programs, viruses, trojans, or ransomware, it will be identified and blacklisted by security companies and antivirus software. When users try to access these websites, browsers or security software will issue warnings.
Phishing
Phishing refers to deceiving users into entering personal sensitive information (like passwords, credit card numbers) by disguising as trusted entities (like banks, social media, or e-commerce websites). If a domain is found conducting such fraudulent activities, it will quickly be blacklisted to protect user safety.
Copyright Infringement and Illegal Content
If a domain is used to provide pirated movies, music, software, or spread illegal, pornographic, or violent content, it may also be blacklisted by relevant agencies or service providers.
Platform Policy Violations
Some domains may violate specific platform terms of service. For example, if a domain is used on advertising platforms (like Google Ads) to promote fake products or deceptive marketing, it may be banned by that platform and affect its reputation on other services.

What is VirusTotal
VirusTotal aggregates data from numerous security engines and URL/domain blocklist services. Through queries, you can clearly see whether this domain is marked as malicious and how many engines have given negative evaluations.
This allows you to quickly assess the domain's reputation. A brand new, unused domain will typically get a “clean” report, while a domain that has been used for malicious activities will get numerous “malicious” flags.

Tip
VirusTotal is just an aggregation tool that provides reference information. It doesn't provide “absolute security” guarantees, nor will it remove viruses for you. If a file is flagged by a few engines, it might be a “false positive.” Therefore, you need to judge based on specific circumstances and not rely entirely on its results.
