CZ responded to the "account hacked" incident: Unfollowed some accounts simply because they were inactive for over 30 days.

BlockBeats News, September 7 - Binance founder CZ responded to the reason for unfollowing some accounts, stating it was solely due to inactivity exceeding 30 days.

Previously, CZ's official Twitter unfollowed some Binance Europe-related service accounts, which was once interpreted by the community as CZ's Twitter being hacked, and also led to some hype around Meme coins.
