Reddit's up/down votes aren't really transparent, they're obfuscated by (imo reasonable) anti-bot measures. It is open source so it's a transparent enough system, but between that obfuscation and pseudo-anonymous moderators I wouldn't say it really matches the request. I completely agree by the way that moderation is essential on popular and large websites, and I think Reddit has a great balance.
