This is going to be a much-heated discussion for today. Read all the comments if you want to understand better.
Hi! I would like to point out that this theme and many others in top 100 are mentioned as examples in reviews because they are allowed to: Use demo content
Create content using pseudo custom post types.
Use contact forms (plugin territory) enabled by default.
I know this is an old theme with 100k+ users, but this doesn’t mean you can’t do a few changes that will get this theme on the same page as new themes (which are required to follow the guidelines).
Things that must be changed:
zerif_register_default_widgets() - this functions adds widgets and demo content into the database. Your current users have already saved this info, changed it. It shouldn’t be a problem to remove it.
zerif_ourfocus, zerif_testimonial_widget, zerif_clients_widget, zerif_team_widget are pseudo custom post types. This should also be removed, if you are still worried about backwards compatibility, you can try and check for theme version and for new installs make sure it follows the rules.
Contact form: you were asked by a few admins to remove it some time ago when you didn’t have so many users. Since then, you’ve managed to add recaptcha (which is plugin territory)
