Self-voting is something that whales are mostly using and I've observed that some give themselves 100% Upvote and when they are curating others' content they give 1% which in some cases is negligible. This doesn't help the Hive ecosystem which is truly powerful when has wealth distribution.
If it were after me, I would remove the self-voting feature which I think would bring more engagement even from whales which in a specific percent (even if little) might care to whom to spread the upvotes.
