deleting your account also wont stop them from finding your new accounts, they mostly archived that as well. they look at browser fingerprinting, device, device components, time zone discrepancy, browser size and VERSION, resolution,,,etc. if you use any paid service/trial service that can spoof any of these above and they arnt the correct versions, they can detect that.
and then theres the warming up period with new accounts(like not posting, reporting, or upvoting too fast after account creation)
