If you start with the proposition "Anyone should be able to post anything on Twitter"...
... and want to get to "Everyone enjoys reading Twitter," then there's a lot of black box space in the middle.
You can have the most vile things on your platform, but your userbase self-censors. E.g. crowdsourced shadow-banning / down-voting. Or reputation with verified identities underneath.
Or just... more transparency.
Empowering the public to data-mine Twitter opens some interesting windows to a platform that has terrible things, but empowers interested parties to fruitfully research who they're coming from.
