The website so far consists of a feed of short posts by Trump on a range of political matters - the most recent of which take aim at Republican colleagues who have fallen out of favor with the former president, including U.S. Rep. Liz Cheney and Senator Mitt Romney.
In Facebook's case, it initially blocked Trump from its platforms for 24 hours for two policy violations before extending the block "indefinitely and for at least the next two weeks", as President Joe Biden transitioned into the White House.
Trump has remained undeterred by the bans, sending out frequent statements via email and on Tuesday launching a blog-like website that he billed as "a beacon of freedom" and a "place to speak freely and safely".
Twitter Inc and Facebook have both removed content posted from other accounts that they said tried to circumvent their bans on Trump. "It could also alter the way that social media companies treat public figures going forward".
After his exile from social media, Trump and his supporters accused big tech companies of "suppressing free speech".
After the Capitol riot on January 6, Twitter banned Trump for breaking its "glorification of violence" rules, departing somewhat from precedent to take possible interpretations of his tweets into account.
Both Facebook and Twitter have called for input on their rules after facing intense scrutiny over their handling of USA presidential election and the storming of the Capitol by pro-Trump supporters.
"Facebook set the rules, are judge, jury and executioner and control their own appeals court and their own Supreme Court".
Regardless of Facebook's decision on Wednesday a Twitter spokesperson said that Mr Trump is permanently suspended from tweeting. YouTube CEO Susan Wojcicki said the suspension will be lifted when the company determines the risk of real-world violence has decreased.
