Hello there! 👋

I am also new here so I don't know everything also.

1. I think it's kind of split 50%/50% for the original poster and 50% for the upvoters. Then the upvoters split the income again by their vote weight.

2. If you follow many other hivers you want to upvote you can lover your vote weight in order to vote for more posts since you can't vote endless.

3. I don't know but I do not see that feature on PeakD wich I use. I don't know if other frontends can do that?

4. Sadly no idea, I don't had the need yet to block someone ;)
