I am pretty sure that you can upvote most of the stuff on instances you don’t have an account for. However some instances require you to apply for an account rather than just singing up (eg Beehaw was like that for me). An admin has to manually click a button for you to become a member. In those cases you can not just upvote or comment on one of those instances without an account. I think it’s to prevent a flood of bots on some of the instances. Not entirely sure if I got it right, though!

I truly think the “moral shackles” could be the reason/key Ukraine can and will win this thing in the end eventually. They realize that the Russian World and way of doing things will inevitably lead to more destruction/war/corruption/bleak future than taking a stand and trying to turn this ship around. There will be more dying and war and internal problems but in the end Ukraine has it in it to do the right thing and what is best for it’s people.
