Good points. Yes, I do prefer to give an instance at least the benefit of the doubt. Difference tho really with Fediverse is you have to search and follow stuff to see it. It does not get inserted into your feed through ads or people playing the algorithms. So generally I'm only seeing what I follow. I suppose we do need to choose our instances wisely. Certainly, if an instance (not just a user on it) is really spamming or impacting on other instances, I suppose there can be grounds to block it. But we have not all been spammed yet by Threads. I don't like Threads (cancelled all my accounts years ago) but I left a few good friends and family there that I would like to reconnect with, and follow them. I also like that my metadata stays on the Fediverse side, so I don't need a Threads account or their app tracking me.

I just would not like to be denied the option to even reconnect with my family and friends. Same goes for WhatsApp interoperating on Signal protocol - I have many friends and colleagues I left behind on WhatsApp, and would like to reconnect again with them.
