Verify it yourself: the manifest is the exact JSON whose SHA-256 is f2be016a4670e0f32a27dac54b9a062f35f74c361d5060403cadb6f6b88866ce; it binds the tweet id, author, post time, and the SHA-256 of the text above. Re-hash the text to match 8d4bbdd1fadd19bd2b0f35c33d8b3a570f0f715a9af376a537a759be7942d4ce, and read the anchor transaction's OP_RETURN bsv.cx / x1 / f2be016a4670e0f32a27dac54b9a062f35f74c361d5060403cadb6f6b88866ce — the block's timestamp proves the post said this at or before that time, with no trust in bsv.cx.
