We (we is litterlayer.com) do not track you. It's possible that our web host could collect your IP address. We don't know or care! When you surf the web, websites typically at least collect that. It's not a big deal. Other than what our web host might collect, we do not collect any personal information. Well, your website of course. This is a search engine so webpages are collected. So, if you put something personal on a webpage, that could get collected. Honestly, we're sad that we even felt the need to type this out. If more websites were like us, there wouldn't be the need to say silly things like, "this site may use cookies." Because, yes, this site may use cookies but pretty much every website does. Things like using cookies to remember your computer visited before is just the natural way the world wide web works. The lawmakers who have made things like cookies seem scary are partially to blame for ruining the Internet because cookie banners are annoying.
To remove your website from litterlayer.com, update your robots.txt:
User-agent: PatuBot*
Disallow: /
Also, put nothing but the word "block" in a patu.txt file at the root of your site (where your robots.txt is).
Why both? Because robots.txt will tell Patu to ignore your site in the future so it's not re-added, and having "block" in patu.txt will remove your site if it is already added. Once you see that your site has been removed, you may delete the patu.txt file.
This will not remove your site instantly. But the next time Patu crawls over your site, Patu will spin it up with its glorious, silky webbing, and kick it out of its orb (your site will be removed from litterlayer.com).
