What about engagement based voting power? The more you engage with the network by voting, commenting, posting, etc. the more your vote is worth. It would be easy to limit the posting rule to something like the 4 rule we used to have to prevent abuse in that regard. It would be pretty easy to spot abuse through comment spamming, just look for the meaningless spam comments that we all know and flag them, and I feel like it wouldn't be too hard to spot abuse of multiple accounts. Even if someone did make a thousand accounts to try and game the system they could only gain voting power if all of, or most of, those accounts actually engaged with the platform. Comment spamming on those alt accounts wouldn't gain them voting power because the comments would get flagged, and they could only post to the daily limit so their power would be held back in that regard as well. Plus even if they did spam post constantly every day to try and build power through that one area, that could quite easily be spotted and flagged.
