I don’t know, and thank you. For instance, very occasionally I may see a mastodon post cross my feed on any Lemmy account; but I signed up for mastodon because I couldn’t access a Lemmy artist’s account without an account, and now that mastodon account is rejecting the credentials I used to create the account. What I do know is that both Twitter and bluesky tend to delete certain posts that touch on too sensitive aspects of any government’s political and legal shenanigans; mastodon almost certainly will too, but the more platforms, the more chance important developments will be noted by regular users before deletion.
