I just assume that the far-right nutjobs are a small minority and as long as this is true, I prefer them getting drowned in one huge community over many small walled communities which only federate with a small group of similar-minded instances. Thats all. Basically the same as we had on Reddit with one large community but many different /r/ Its totally fine if you have another preference. I didn’t want to blame (leftist, general interest) instances of anything, either. Of course they have the right to kick out everyone they don’t want to give a platform (i also blocked many people on REddit over the years). IMHO Reddit worked very well as a platform with almost everyone on it, though. Till today there are many subs were a civil discussion can be had despite far-right and far-left potentially meeting. I don’t know of any for-profit commercial social media wih comparable discussion quality except specialised platforms like StackExchange or HN

When Mastodon was tiny but already stuck in the left-right battle, the banning was just getting a bit out of hand imho. Some Mastodons allowed everyone in, some hat a banlist of far-right instances, some only federated with explicitly pro-LGBTQ instances (but always incompletely, since the community is always rapidly changing). This makes it difficult for new users to choose the right server. If Lemmy/Mastodon/whatever has 100 mil users or more these things stop to matter, of course, because there is always enough content even if some highly specialised instances are missing. But before we reach that point I would rather have one large platform growing, then branching out

GTIO is an interesting concept, though, and solves the problems I assume maybe. Thanks for the link, I didn’t know about it, will check it out
