Yep, I was also shadow banned from my local city subreddit shortly after being blanked banned from several other subreddits for simply participating in unrelated subreddits. Shadowbans are particularly problematic in city based subreddits where people are more likely to actually try and connect for something in meat space. Missing persons, lost pets, etc. We found a stray pet, but it took my wife creating an account, to finally connect with the owner via reddit despite me having had a 10 plus year old reddit account that was shadowbanned for our city.
