I joined because Reddit has become a cesspool of bots and toxic behaviour. Lemmy is still completely open-sourced, while Reddit isn’t at all now. Also, when you first sign up on Reddit currently, you get completely ignored now and can’t post or comment on regular subs.
i never used Reddit, but came from 9gag here in the search for something where you can actually filter the content. being foss and decentralized (both of which I’m a huge fan) was an added bonus
