I've archived public comments posted on Youtube, not all, but about 20 billions so far, from 1.4 billion different users(I archived user information too)

I've made a tool to search through this database, allowing to input a user, which outputs the comments they've wrote.

I've stopped the crawling due to the server cost though, so this database may not be expanded further. I've achieved this amount in 40 days~

This is a paid tool and while I do of course remunerate myself, I also use a good chunk of the money to make new tools and improve current ones, I've been doing that for the past 3 years now and the set of tools on my website grew that way.

If anyone has any doubt I can do test queries on users you'll give me :)
