Friend chain needs to meet the following requirements:
- Independent blog, independent domain name.
- HTTPS is enabled on the entire site, and HSTS, HPKP, DNSSEC and DNS CAA are enabled, and the site security test level reaches A+.
- No bad content on the site, and no external links to bad sites.
- The website has not been blacklisted by the Ministry of Industry and Information Technology, has not been marked as a bad website by security organizations, and the website domain name and server IP address have not been blocked.
- The website does not open too slowly, you can use the CDN service.
And, this is only a basic requirement, this site does not accept friend chain requests, but if you and i are familiar, i will add it as a collection backup (but only if you first let me know that you have at least one such website), those who actively request friend chains will refuse.
Unfortunately, i don’t have many friends (that does not mean I don’t have friend).
