Would it be possible to boost other people's posts? E.g. You want to post a link to a useful Bitcoin website, and see that someone already posted it December 1 2021 but only received 2 comments. You want more people to know about this website (but don't want to make a duplicate post), so you boost this post with 100 sats and it appears in "top posts" again. Or is this already included in the algorithm?
