As someone who has been boycotting Reddit since the API-enshittificationing, I can’t help but echo SpaceNoodle.
However.
Did you make sure your IP address has changed? Typically dynamic IPs don’t change very often unless you disconnect your router and/or modem temporarily (and sometimes even that won’t do it.) You’d need to check what your public IP is, restart or disconnect-and-reconnect your modem to get a new IP address, then check your IP address again. Unless you do all that and confirm your IP address has changed, it’s risky to try again on your laptop.
Also, you’ll want to clear more than just your Reddit cache. To be safe, I’d recommend clearing all your data in your browser. Cache, cookies, history, local SQL, all of it. And for all domains. (I don’t know to what extent Reddit may use other domains for things like authentication and such. They might still be able to tell you’re “you” even if you clear all the cookies and such for *.reddit.com.)
















Reddit owns/uses multiple domains and the multiple domains can certainly collaborate to compromise your anonymity (or at least pseudonymity) even with third-party cookie blocking enabled. For instance they use
redd.itfor url shortening like this url. You could clear all your cookies for*.reddit.comand perhaps hide that you are the same user they previously banned for a while, but ifredd.ithas ever set any cookies that you haven’t cleared, the first time you visit aredd.itit could reveal your identity to Reddit. They probably own quite a number of other domains that might similarly reveal your identity to Reddit, and there are most likely third party companies that own other domains that will collaborate with Reddit in some way or another that will reveal your identity to Reddit.
