A better comment policy would be to stop censoring random people (like myself) for having controversial opinions. Your article assumes that users are afraid to mention controversial opinions, but I would argue that most users are not afraid of this, especially in the WordPress community where everyone has different agendas.

Last week, Sarah deleted one of my comments because she said it sounded like a "personal attack." This is very interesting, since many controversial and even insulting comments are regularly published here at WP Tavern when posted by certain individuals... this is of course your choice, as a property of Audrey Capital. But assuming your mission statement is in good faith, and you really do want to create a website for open discussions, such decisions are self-defeating and expose a rather bitter sort of hypocrisy.

Encouraging anonymity in a community that's rife with consumer fraud, fake reviews, spam, affiliate links, and secret quid-pro-quo deals is a very bad idea, frankly...

Enabling users to update/edit comments is a better idea, alongside requiring real names. This allows people to fix their wording, change their mind, or so forth while still being honest about who they are and what they think, without worrying about permanency.
