I put Mastodon on a back burner as it's just too clunky (for me at least) and am currently interacting with people from all over on BlueSky. Half the time on Mastodon (various apps/instances, web, or browser) I couldn't even log on.
BlueSky will probably go the way of others. Yes, there is a troll problem, and you need to be wary. But I had the same to a lesser extent on Mastodon.
In the end, I've had to accept my relatives, work, and old Army colleagues will never be on there, I've become resigned to that and keep a WhatsApp account for that reason.
Before getting on our high horse - there are mercenaries of various nationalities fighting on the Ukrainian side as well as the Russian side, that doesn't mean their governments support them.
