Well, that’s true but it’s the dummiest you can get with Google nowadays. Creating a new account through Gmail also requires to add a phone number. You can only come around that via an old device. You cannot come around device identification however.

1. Find an old Android device (Phone, TV, tablet etc.)
2. Factory reset.
3. Create a new Google account.

Even if no trackers (which there are) Lemmy is federated so you cannot just delete your stuff and sleep over it. However if you need to be careful, you can solely use Lemmy over Tor. It’s not private but can be anonymous.

I think I recently read that Lemmy devs are working on private upvotes / downvotes (yes even they can be tracked) but it seems it’s tricky with federation.

So, generally Fediverse is not private and cannot be private due to its nature. If you have a threat model, you should use it with Tor.
