Voting doesn’t actually work with platforms. People voting may not have access to the required information. Having a single or council of people to actually who actually understands what is happening in our society do question answer with other individuals is the healthiest way of doing things.
I can get into detail about why if people actually want to create a healthy platform.
The main thing preventing that is capturing of initial user base.
The next part is finding a person who has some understanding psychology and know what a healthy community looks like to moderate.
Something like a code of conduct is typically the correct way of doing things. Neither is strong moderation abilities, since almost all moderators are influenced by other users and their own opinions.
