Couldn't you just use cookies to track which creator a user visits and how often? I doubt many people are willing to install a extension for that.

Nope, not possible on any content site (eg youtube) and it also needs the site to add it.

Neither would it give us enough data to create what we have done. The algorithm in the extension is smarter about what it flattrs than a cookie could ever be. And more privacy friendly too.
