On reddit, you can’t post basically anything anymore. Go to computerscience, programming, gaming/games… You can’t post ANYTHING. No matter what you post, removed… It sucks. It’s like 1% of people get to post, everyone else is muted…
But lemmy is better. Here, things are fair, there aren’t over-moderation and too many rules. How do we get people here? No one wants to join lemmy.
I find it hard to believe that those communities don’t allow most new posts. Are you sure it’s not a you thing?
Most subreddits have a karma barrier where brand new accounts can’t post. It’s shitty, but it helps prevent bots.
