Tor's not enough if you want anonymity. Stylometry is the first thing that comes to mind for de-anonymization over Tor. Your writing style can give you away instantly, so consider using something like Anonymouth to rewrite your posts before you make them.

The way you (physically) type (as in typos, typing speed, etc) is also very effective at breaking anonymity, so use software like kloak to get around that. Whonix comes with kloak already, so if you're using it (which you should be) you don't have anything to worry about there.

Consider browsing over Nitter as nostr:npub14a6q6xvt4wuv0wpdpfr336e4fweldtu6np3ehpw55h83xuw2h2zsgyz6rn said, since you want to limit your exposure as much as possible (especially on proprietary platforms).

This isn't even the tip of the iceberg, just so you know. True anonymity online is a rabbit hole that you'll spend a huge amount of time going down if you're serious. It's stupid for me to even give this advice in the way that I am with an identity tied to so much of the stuff I do online, but I don't have any plans to utilize the info so I might as well share it before I end up forgetting it.

Have fun on the tinfoil road! You'll get burned out if you don't :)
