I made an account 3 years ago to make a single post, which I wanted to be anonymous for. I logged in again today as I wanted an account for... um... science, and discovered I was banned a year ago. I find this ban incredibly odd as
I did not log into this account for two years between the post and the suspension
They do not state what rule I broke, which is not standard in my experience
They do not offer the opportunity to appeal, which I also believe is not standard
They tell me to make a new account. If I broke their rules, why would they want me to make a new account? Temp ban makes sense. Permaban makes sense. This makes no sense.
The only explanation I can think of is that they want to bump the user count.
If you have two reddit accounts, and one gets banned, if you log into the other on the app or on the web with the same device then that account will be banned as well.
