There’s some assumption that the text in comments should be parsable as Markdown but there’s probably nothing stopping you from storing some JSON.

Have you tried it, does it work?

I have a small proof of concept, yes. I request the list through the v4 endpoint and just parse all the comments as JSON.

If it works, go for it. It’s your list.

All right, thank you. Would this also be ok if, at a later date, I allowed users to authenticate with their TMDB accounts and would store things in their lists?

In theory, sure. You’ll have to balance that in practice though.

The new list layout is being launched soon which has the ability to show and hide comments so in theory at least these users could hide all the gibberish JSON from polluting their displays.

Ok, thank you for the quick replies and permission!
