Hi, 

I am preparing an experiment that involves communication between participants using a custom live page and JavaScript (instead of the in-built chat function). We want to deter participants from being aggressive to one another or revealing personal information (beyond using the fine administered post-experiment), so I wondered if anyone has experience with integrating a profanity and/or personal information cleaner into oTree, or has any idea how I might go about doing so?

Any advice would be greatly appreciated.

For the profanity bit... perhaps as part of the live page code in init.py, you can send the writer's text to a 3rd party API (like Google's Perspective API https://perspectiveapi.com/) and if it meets some threshold, censor or give the writer feedback before sending it to other participants. Not sure about the personal information problem though.
