If I ever have enough money, I’m thinking of setting up my own small server and migrating Lemmy to I2P. A Lemmy instance with the same features, but running on a completely free and anonymous network. Everything will be allowed except for moderation regarding serious topics and spam. It’s a nice thought, even just imagining it.
Hard to pierce pseudonymity doesn’t interest me that much, because it’s bad enough having all your posts connected together.
I want something like 4chan (but heavily moderated), where all posts are just marked “Anonymous” and if you make 3 different comments, it’s not publicly shown that they came from the same person. It’s ok to retain the info privately for a short period, for moderation purposes. It could be ok to assign a persistent pseudonym for each thread, so if you comment 3 times in the same thread, those comments are connected to each other, but not to other comments in other threads.
This is a good article about the attractions of completely anonymous posting, though it’s from the pre-supertoxic internet era: https://wakaba.c3.cx/shii/shiichan
