Hey, thanks for posting this here. Good to have a discussion out in the open about this.
Our official comment moderation policy is listed here on our FAQ page, but I pasted it below for anyone wondering what it is:
We will only moderate comments as if they fall under one of the two categories below.
If a user is spamming unrelated or irrelevant content (e.g. links to other pages, links to experiment campaigns), then that user will be warned once. If the spam continues, or it's clear that it's robotic, then we will ban the user.
Abuse / Harassment
In the case that a user is insulting, harassing, or creating an overly negative environment, then shadowbanning may be used. In most cases, a warning beforehand should be sufficient, but if it’s clear that the behavior will continue, then a ban will be put in place.
You're definitely right, researchers should have the ability to flag comments for review. This is a valuable feature that gives more power to the scientists, so we'll figure out how to prioritize it and make it happen.
