Reddit has made a partnership with Google so that the same identification technologies developed by Google will be used by reddit to block out all anons. The technology is gradually deployed and in its final steps you won't be able to have a reddit account not tied to your personal phone number.
Right now, using a VPN means your reddit account will be suspended. The same holds for any account flagged as not fitting the reddit profile. If you check r/help on reddit, you will see lots of users trying to understand why their accounts have been suspended out of nowhere and why they have entered a loop of being told to reset their password only to be suspended again.
In typical reddit fashion, users ask for help on the help subs and reddit admins respond that they are doing their best to remedy the problems, but when other users post a workaround, the loophole is quickly closed.
As you can see, reddit tries to become ready for the next US elections. Currently, bots are active deleting older content, starting from years back. For example, posts made a decade ago are suddenly removed without any explanation.
The best way to combat this is to stop feeding reddit with content.
