We know this because he immediately tried to launch a workaround with Twitter (who also banned him).
Trump has a website that's essentially a blog for him to perpetuate The Big Lie. Followers can "like" and circulate the posts on social media, but that's as far as it went.
His new Twitter website (an extension of his blog) - was launched on Tuesday and shut down on Wednesday. In bold headlines Twitter suspended Trump's - @ DJTDesk account - which violated Twitter rules.
Perhaps if Trump and his minions were able to read something other than Dr. Seuss, they would have noticed Twitter's rules and policies page, which leads to their policy forbidding people from circumventing permanent suspensions.
Trump was de-platformed back in January, after his supporters violently stormed the U.S. Capitol in an attempt to overturn his 2020 election defeat.
There's little doubt that Trump will continue to try to utilize social media in any way possible. He's already tried to get around Twitter by having his supplicants rebroadcast his blog rants.
Those attempts have been plucked from the Twitterverse and suspended. But new ones keep popping up.
It'll always be a challenge as long as Trump continues to use every resource to circumvent his social media bans.
As an authoritarian populist, and someone who doesn't believe in Democracy, Trump's legacy will be toxic for years to come.
