Single best thing I've read on Mastodon yet.

Twitter users have "been taught to behave in certain ways. To chase likes and retweets...To promote themselves. To perform...They call themselves 'refugees', but to the Mastodon locals it feels like a busload of Kontiki tourists just arrived, blundering around yelling at each other and complaining that they don't know how to order room service. We also mourn the world we're losing." #twittermigration #twitterefugee

Home invasion - Mastodon's Eternal September begins

The fediverse is dealing with a huge wave of Twitter people bringing toxic ideas with them.

@mlmillerphd I wonder if there is still not some possibility for refuge and self-protection, despite being a newcomer myself (although I have been a #TUINO (Twitter User in Name Only) for a long time. Admittedly, I only fully deactivated my accounts a couple of weeks ago. I have been trying to learn and respect the culture gradually, with quite a few gaffes and faux pas along the way, even if perhaps it is changing or dying.
@mlmillerphd However, a Mastodon instance is neither a bus nor a public service, and no admin is obligated to accept everyone or even anyone as a member. There still might be room for out of the way places in individual instances where people can exercise autonomy over how their communications take place. This, once again, would seem to be one of the service’s particular virtues — people have comparative freedom to set their own rules. Am I missing something?
@billday no, that sounds right to me.
