And then the wider Mastodon big instances. This is inevitable, whether you block Threads or not, any tech savvy celebrity that chose a Mastodon instance is now on Threads. Instance blocking Threads will cause those who follow that person to move over to a centralised Mastodon instance that hasn't blocked Threads. From here they will continue to follow / interact with them if they choose to.
