If a website could be sure none of their users are malicious/bots and all of the users are perfectly rational and virtuous then public or private voting wouldn’t matter either way. That being nearly impossible, why not a reputation based system like Stack Exchange? Only when an account meets certain requirements they can vote.

To boot, on the website tweakers.net one can actually vote -1, …, +3.

• +3: “Spotlight comments are of such high quality and substantive value that they clearly stand out above the rest”
• +2: “Informative and interesting comments that are a useful addition to the discussion in an on-topic thread or the information in the article”
• +1: “Nice on-topic responses with knowledge that is common knowledge”
• +0: “Comments that do not contain a relevant contribution, but are posted with good intentions”
• -1: “Flamebaits, trolls, misplaced jokes, unnecessarily hurtful comments and other comments that violate our terms and conditions or house rules”

Immoral baskets that incentivize greed are to be avoided.

Then they should transition away from multi-level marketing pyramid Ponzi schemes too. I deleted my Protonmail account when Proton began peddling crypto“currencies”.
