First of all, please note that if you want to say something in the club, you should post it once. You posted it to the club notes, to this new topic and also to 1 more topic. So, you said the same thing 3 times. Please respect other club members and moderators and they will respect you.
Secondly, we informed players (multiple times) that the chats are saved in the archive now.
Thirdly, team chats (teammates talks in Teams games) are hidden for privacy reasons and even chess.com admins cannot read them.
Fourthly, the games are not private. Spectators can watch live games and see the chats. (And this feature exists for months.) So why cannot they read chats in the archive?
I've learnt that the archives of previous games and messages are now publicly accessible by anyone. This is a blatant breach of privacy and it should've been worked through with great care. I urge the developers to remove the archives of games before the latest major update. Chat messages are intended for just the 4 participating players and not for anyone else, that is at least how I believed the policies work. Please do something.
I have also notified the CHANGELOG group.
