I don't think Patreon does. As you can see you cannot see that information for every creator.
Publishers/creators can choose to show or hide the number of subscribers and their monthly earnings. This site simply is scraping that freely available information.
Note that this wasn't the case in the beginning. It was only at some point that Patreon gave creators that choice - and I believe the default was to hide the earnings (but no the number of patrons).
