Q&A for How to View the Tweets of a Twitter User Who Blocked You

A user might block you if they perceive your interactions as negative or unwanted, or if they simply wish to limit who can engage with their content. It's also possible they blocked you accidentally or mistook you for someone else.

The only way to currently view private tweets is if the account owner gave you permission to view them.

No, there isn't. There is no way to know what time a user blocked you, unless they did it when you were viewing their page and refreshed.

Neither. That isn't blocking at all. If someone blocks you, it will say you are blocked from viewing the profile. If a profile is empty and says the account doesn't exist, that means the person has deleted their account. A private account will say the tweets are protected, not that the profile can't be found.
