In case you missed it, StreetPass is a free open source web browser extension which helps you find accounts to follow on Mastodon:
After you've installed the extension, just use the web as normal. Your browser will start noticing if sites you visit have Mastodon accounts, and will make a list of these accounts.
(Owners of websites need to have a verified link to their site on their Mastodon profile. More info here: https://fedi.tips/how-do-i-verify-my-account/)

The "How to get verified" sites tend to neglect an important fact. The verification mechanism limits itself to sites something like less than 2mb. My favourite method for web content starts at 2mb. So I had to make a special page for verification.
Basically, there's no real reason for someone to visit my verification site. And I suspect that I'm not alone.
I suspect that you could browse all day and not collect any interesting sites/accounts.
At the time I played with it various ways. My recollection is that it didn't want to "eat" any page that was more than 2mb, no matter where you put the header.
It's probably not worth it to try again. After all the effort, the verification only appears on your profile page, and not next to your posts.
