I totally support this. It still amazes me that companies still do not delete/anonymize user accounts after periods of inactivity. Everything that is linked to your email address should be purged after 3-12 months of inactivity, including ecommerce like Amazon, game platforms like Steam, cloud storages like Dropbox, or even Hackernews. Good luck trying to find old accounts that you have used years ago, what if they were breached and now they are used by people with bad intentions. In my country (Romania), even barber shops that store user accounts for longer periods than necessary are fined the shit out of them for not closing accounts due to inactivity. Some years ago, I woke up with an inactive G2A account telling me that I have to pay a fee for inactivity. NO! I don't have to pay anything, purge it!
