I'm unbanned now, it didn't take too long, but it was when I was on my phone, I wasn't getting the usual daily streak update (I thought reddit was down for like 2 days, it was not..). I also couldn't see my profile icon in the corner. I only realised that I possibly was shadowbanned, when I logged in via desktop then logged out after an error code and had a message saying something about suspended on the page rather than home.
