So my question today is:
How will mastodon be governed? What's to stop the bad guys opening up instances and joining the federation?
Who says that subversive content is not allowed and should be taken off the instance, or banned.
Lots of challenges for a nascent platform I think..

@eileenb My understanding is, there’s nothing to stop “bad guys” from opening instances. But “good” instances needn’t link to them.

Of course, that doesn’t stop a bad guy from sneaking into a good instance and causing havoc from there, but the local admin can then ban the bad guy.

In meatspace this unlinking and banning would be considered dictatorial, but here? Find an instance that’ll tolerate you; failing that, build or buy your own: not that big an undertaking. /1

@eileenb In case I wasn’t clear, I put quotes around “bad guy” for a reason. We needn’t agree on who’s good and who’s bad for this scheme to work well for everyone: everyone, that is, who isn’t interested in suppressing others’ speech altogether. /end
@babelcarp some great points there - some 'bad guys' are only bad due to differing opinions.
some folks totally agree with Sharia law principles for example, whilst others are utterly opposed to it.
finding a solution that would suit everyone in the fediverse would be impossible...
