Na, apparently they do have the ability to track who and where you make accounts.
I've similarly made efforts to discuss and condemn the brutal genocide in Gaza on reddit and found myself with a perma-ban.
I'm only going to hazard a guess, but somehow reddit knows which devices your accounts have previously been logged in on, and will automatically ban your new account after 1 day.
I've tried using VPNs, virtualized desktops, different devices, made accounts on devices that I have never logged in on, but then when I use the new account on my regular device, it gets banned.
Spez got a taste of that good Israeli money and now outright bans users for questioning or criticizing the Zionist machine. Welcome to the weaponization of the greatest tool humanity ever created - the Internet.
