one thing i would add is to make small accounts minimal votes of 10% on posts.
this 1% votes from accounts that have less than 5000 SP are only irritating.
of course whales 1% is different so i would just make this rule for some chosen number of STEEM POWER that makes any difference on posts.
if all small users on STEEM wil lvote on all posts 1% the blockchain will raise to big numbers without any good from it.
This already exists to a certain extent. I think your vote has to be worth around 5SP for you to be allowed to make it... so like a 50SP account can't cast a 1% vote, but a 500SP account can (just barely)
possibly but i think that should be moved to 10% at least
