Another widely circulated post claimed to be from a former paediatric nurse, and claimed to indicate that there was something suspect about some part of the image. There is nothing to indicate that any of those posts were actually legitimate, either.
Very soon after, senior journalists and Conservative candidates began sharing those same claims. Former England cricketer Kevin Pietersen, who is followed by three million people on Twitter, shared the post on his account.
The text of the tweet was also shared onto Facebook, which helped increase its spread. While some speculated that the post was being amplified by bots, many apparently real accounts were seemingly copy and pasting the tweet to share it.
