I think there is some kind of IP or cookie based identification going on.

One of my accounts was permabanned on the German /r/de subreddit for publically questioning a mod decision. At the next login I found that ALL of my accounts that I used for serious and professional subreddits (netsec, python, learnmachinelearning) and never once used on /r/de had also been permabanned.

I wrote to the helpdesk but they only told me to contact the mods of /r/de which is impossible if you're permabanned.
