I don’t know Tommy Robinson that well (in the UK), but here is his one hour film "Panodrama: An Expose of the Fake News BBC”. This is his side of the story. YouTube is allowing it now, at least.
In the byline, Robinson claims that BBC coaches people before interviewing them, in making a “Panorama” program.
Facebook removed Tommy from FB and Instagram apparently after this documentary was published (Tim Pool’s video yesterday suggests a connection).
He talks about jail time for earlier activism and solitary confinement.
He also talks about an anti-fascist group whom he claims works with media.
It is always difficult for social media and payment processor companies to judge accusations of hate speech objectively. I had heard very little about him in the U.S. but the details in the latter part of the Wikipedia story are disturbing.
