First choice to make for a social media platform - do all user should have (a) the same vote power or (b) there should be power levels?
If choice 'a' - there is no much more to add.
If 'b' - what should decide about levels / power allocation?
a) number of followers
b) wealth (in tokens)
c) experience on the platform
d) number of posts
Hive (and its predecesor - Steem) has the model of 'b' + 'b', thus the rich downvote trolls play by the rules and, in the name of the justice, there probably nothing shouldn't be done with them.
