you would like to "verify" yourself on the fediverse? great, no problem.

1. go to namecheap.com
2. register a domain, get their cpanel hosting or whatever.
3. put some website up on said domain, include something like <a href="[YOUR FEDIVERSE PROFILE LINK HERE]" rel="me">Follow me on the Fediverse!!!!!11111oneoneone.</a> in your HTML. the rel="me" is important.
4. link to your website in your fediverse profile.
5. the software will mark your relationship as verified, have a nice day

myself and a few others built this in 2018, seriously, we solved this problem years ago. it is how the internet works.
