| Purpose | SEO and backlink crawlers. Commercial indexes sold to marketers. Blocking them hides you from their customers, not from Google. |
| User-agent contains | mj12bot |
| robots.txt | User-agent: MJ12botDisallow: / |
| How to verify | No published verification method. Treat the name as a claim, not proof. |
| Should you block it? | Charge it; it is a commercial product built on your pages. |
| Does it pay? | No. It does not carry a wallet and cannot answer a 402. A site that charges simply serves it nothing. |
