I just did a fresh in stall of Matomo (latest version 4.13.0) and noticed in the user management section that besides the user account which I created for me while doing the installation with Softaculous, there also pre-exists another user called anonymous with no access and the email anonymous@example.org.
What is this user, is this really only an example of a user account that I can safely delete now? Or is it an account used maybe by some Matomo system service, by Softaculous, my provider, etc. so that I should NOT delete it?
