I use both Mastodon and BlueSky and I don’t really care for platforms like Twitter. Both Mastodon and BlueSky are good in their own ways but I think BlueSky is user friendly. Easy to setup looks super similar to Twitter, easier to navigate.
Plus, I have heard about it pretty much everywhere. It is commonly compared to Threads. I only know and heard about Mastodon on Lemmy.
I think you are asking the right questions, IMO. It isn’t out of the ordinary for this kind of thing go happen there are for sure prevention methods used.
I am far more interested in the failure than the statement itself.
