Seems he already started censoring posts today.
The blockchain doesn't ever see your passwords. If you use tools like Steem Keychain (which will most likely move to Hive Keychain), the interface you post to won't see your passwords either. Changing recovery account is a good idea, but the recovery account alone can't take over your account.
Well, that's good news. Thanks. Did you say Tron is censoring Steem somehow? I wonder how that would be possible outside of downvotes.
