To quote John Gruber's commentary, related to the recent appeals court ruling whereby Trump cannot block people on Twitter:
With the absurd number of replies he gets with each tweet — thousands, if not tens of thousands — I can’t see why he even bothers blocking people. But I like to think he’s actually sitting there, wasting time each day poking buttons in the Twitter app, angrily blocking people.
Is there documented evidence that Trump has actually been taking the time to actively block people on Twitter since he is President of the United States?
If so, is there any evidence that suggests that is Trump doing so personally or, on the contrary, that this is being done by aides?
Edit: To address the concern that got raised about notability:
Gruber's site is popular enough that there's a term to describe what happens when his readers throw traffic at a site (fireballed). Moreover, anyone who has watched US evening shows (Colbert, Noah, Oliver, Bee, Meyers, etc.) with some regularity will be keenly aware that the hosts mostly take it for granted, if only as a meme, that Trump's "executive time" is about playing golf and Twitter. And the claim is also notable to those who follow more weeds-y sources that discuss the machinations that go on in DC and the court system.
