@rysiek This was also my concern, combined with new people signing up and then being on a less well moderated server so they have a bad initial experience before they even understand how the fediverse works or have many friends to help them.
*Edited to add that I understand why this was done but it's a strategy that inevitably would need extra support in terms of very vigilant and active moderators and also doing some sort of waypointing for people towards tools to get to know how to use the fediverse. If you're going to be setting yourself up to be the instance that onboards newbies then you kind of need to do the onboarding part.
