Scaled takes smaller communities into account and bumps their posts up so they don’t get buried by posts from larger communities with more engagement.
Edit: here are the descriptions:
Active (default): Calculates a rank based on the score and time of the latest comment, with decay over time.
Hot: Like active, but uses time when the post was published.
Scaled: Like hot, but gives a boost to less active communities
Yes.
I won’t subscribe, post, or comment in ml.
