This distorts statistics such as number of active users and gives the impression that there are more edits/users than there actually is.
Solved by updating mediawiki-extensions-SimpleBlogPage/src/Hook/CreateBlogRootPage.php at 3e37e67289e6674920bc692b036cf85a472eb38b · wikimedia/mediawiki-extensions-SimpleBlogPage · GitHub to use a system user such as “Maintenance script” or “SimpleBlogPage extension”.
Alternatively I think supplying EDIT_SUPPRESS_RC to $updater->saveRevision might suppress it when counting active users as well.
