Why is lack of moderation a problem on Mastodon?
Twitter pushes content from random users you don't follow, that creates a responsibility to moderate (plus they need to keep the advertisers happy).
The Mastodon timeline is direct follows. If I see some stuff I don't like, I can talk with that person or simply unfollow them.
and the TweakNewTwitter browser add-on rejects it, along with "trending" and all the rest. Add in ublock origin and you've pretty much got Twitter the way I thought it should be.
Having a process that distributes the load of moderation is better, IMNHO, than piling all that work on underpaid people.
How will it be the same or worse? Which member of it?
Mastodon is simply a social federation enabling software; it's similarly abstract to refer to Twitter's software infrastructure.
