Hm. As long as you only interact with Lemmy through a (trusted) VPN, or even through Tor, you’re just as safe using Lemmy as you would be any other website. Servers can always see your IP by default, and the owners of those servers can be coerced to give it away by whatever external forces. If you hide your IP, they can’t. That’s pretty much it.
Lemmy is not designed to provide reasonably-hardened anonymity in the sort of way that Hyphanet, I2P, or maybe Tor or something like that is.
I would not recommend using Lemmy if I were seriously concerned about government prosecution for content on it.
Lemmy’s a good alternative for something like Reddit.
lavender.ltgc.i2p exists. It’s Lemmy instance avaliable from i2p and tor. But it’s mostly pony instance.
