Hi, welcome to the Fediverse buddy. In all honesty can't speak for the reason behind Reddit choices, maybe they are just abusing AI without any proper control.
You can use the search bar to easily find many Communities (Groups) for your interests. Alternatively you can use this search aggregator: https://lemmyverse.net/communities.
In your Lemmy setting you can block NSFW contents, users, communities and even instances if you wish to. Make this your own place ✌️.





You're welcome.
