I don't understand this. The Federated timeline is always going to be full of the same kind of crap that Twitter (and other social media) has. The whole point of Mastodon is that you can avoid that by joining an instance that matches your interests, and then only look at your notifications and the local timeline.

By doing that you can see only things said by, or boosted by, people who you have chosen to associate with. Then you get most of the benefits of social media without getting the crap from the uncontrolled firehose.

But sure, if you want it to be like Twitter, and then reject it because your experience is like Twitter, then by all means. I just don't understand your reaction.
