This hasn’t changed.
CLEARCHAT’s are sent to everyone as it’s an instruction to “remove this message from view” regardless of the permissions of the user connected to chat.
So if you are no longer logging it/seeing it, then you’ve got a bug somewhere in your code or in TMI.js itself.
I have tested this and it still works as expected.
Connected a non mod to my channel.
Then in another window timed someone out.
And my non mod saw a CLEARCHAT with the relevant tags.
Course CLEARCHAT will report bans and timeouts but there are no events for untimeout/unban over IRC.
EventSub or PubSub would be a more optimal way to monitor for moderation events in my opinion.
