No, because now the contents of the tweet are hidden until you explicitly choose to view them rather than just showing up unsolicited, and more importantly, because tweets flagged in this manner no longer show up in feeds. You would have to visit his twitter account to even know that the tweets exist, and you would have to click on each tweet individually to view it, and to waive the warning label, so you would already have to have the intent to view them. Thus, the Streisand Effect doesn't apply.
