@HistoPol It is my understanding that boosts won't be passed on if you block the bridge or add #nobridge to your profile because the boost still has you as the original author. This would be true no matter which software a person is using.

But if someone quotes you (on any platform, not just the ones mentioned) or takes a screenshot of your post, that would not be blocked. And people can do that now without the bridge. Windows comes with software that allows people to take screenshots. So do phones. And most other fediverse platforms other than Mastodon allow quoting.

The fediverse has over 100 different projects and multiple protocols already connected to it. If you are concerned that people will quote you or boost you on other networks, you might want to consider a whitelist servers where you only allow approved Mastodon instances.

With or without the Bluesky bridge, you are about to be outnumbered by Threads, WordPress, and other projects coming online. ActivityPub is an open network, after all. Always has been.

But the nice thing is that you can control who you connect with by blocking or whitelisting. In your case, being on a whitelist server would probably address your concerns.
