We do nag, in that all the green shields will suddenly go bright red. But we don't block the user from being able to send messages until they've resolved the problem.

It's possible we'll reintroduce this once cross-signing has been fully adopted though; it's tricky because we need to distinguish between encrypted rooms where you simply don't care if random users have unverified slides... versus ones where it's a disaster if an unverified session slides in. Finding the right UX for that is tough, but we think the current balance is an improvement.

Alrighty, thanks for your answer :)

That is really a tough UX problem... Maybe a room could have a "sensitive content" flag that is enabled by default for one-on-one chats and can be manually enabled for group chats.
