You should take a look at lobsters. They solve a lot of the transparency issues that some have with HN and ProductHunt.
"Some other link aggregation sites are operated by corporate entities which may have significant financial incentive to censor or artificially promote the links and discussion that relate to those entities, their investments, or their competitors. Some of these sites have had moderators of popular sub-forums banned after it became known that they were being paid by 3rd party companies seeking special treatment of their submitted stories.
All moderator actions on this site are visible to everyone and the identities of those moderators are made public. While the individual actions of a moderator may cause debate, there should be no question about which moderator it was or whether they had an ulterior motive for those actions.
All user voting and story ranking on this site uses a universal algorithm and does not artificially penalize or prioritize users or domains. Per-tag hotness modifiers do affect all stories with those tags, but these modifiers are made public and usually used to shorten the life of meta-discussions. If certain domains have to be banned from being submitted due to spam, the list will be made publicly available.
If users are disruptive enough to warrant banning, they will be banned absolutely, given notice of their banning, and their disabled user profile will indicate which moderator banned them and why. There will be no hidden or childish "shadow banning" or "hellbanning" of users popular on some other sites.
The source code to this site is made available under a 3-clause BSD license for viewing, auditing, forking, or contributing to. This code is always up to date with what is running in production on this website.
Public stats are available for site requests, comments submitted, stories submitted, and users created."
