This page doesn't make sense: you say Tech Companies That Won't Delete Your Information at the top, and then immediately list, e.g. "Outlook Mail: Delete Account? Yes".

This makes them sound like they do delete your account information. If there is something specific that they don't delete, it might be best to highlight that.

Also I am unsure what "Track" means.

And how can you Delete Account be unknown? Did you try? If not, how can you claim they are naughty?
