How did two dog confirm being blocked?

Excuse me, do you want to ask the question "How to confirm that the QQ avatar is blocked"? The software confirms the shielding method as follows:

When the account of "QQ avatar" is blocked, the account status will be set to stealth. In this way, other users will not be able to see the dynamics of "QQ avatar" and send messages to it. "QQ avatar" will no longer be displayed in other users' friend lists, nor will it appear in other users' search results.
