HARASSMENT & MODERATION
Many new users just arrived here simply following the notion that 'on Mastodon there is no harassment' but not knowing why abd how does it work to maintain it so.
Therefore when some of this new users sees a couple of trolls they tend to say that 'there is no difference with Twitter' without further exploration of that.
Let's clear a point: the only way to make social media platform that is 100% harassment free is to give to the users zero liberty and to moderate every single posts before it's published!
Mastodon is famous for his anti-harassment environment not because there isn't any on it, but because 1) his structure permits a series of efficient and immediate actions against bad accounts/Instances and 2) most of the Instances are run by communities that actively work to maintain Mastodon clean.
