thats what they did to mines too, your not alone. i think they even consider deleted accounts that were sub banned, then any of your old accounts that participated in that sub even before one of your accounts was banned, it counts as ban evasion. so its a retroactive ban.

like me, im hearing from the shadowban sub, 5-10+year accounts are getting instantly annihilated by reddits AI bans.

before you just use a different account and avoid that sub, but now having more than 1 puts you at risk, if even one account is banned a specific sub, and any of your other accounts participated in that sub in the past they count it as ban evasion.

if you search a deleted account that was shadow or permaban, it still shows up on incognito as "account was suspended", so they definitely keep tabs on deleted accounts that were banned,.
