Vaughan said days after the match she was informed by her club that she needed to provide a statement because she had been reported by a member of the opposition club, via football anti-discrimination body Kick It Out, to her local county FA.
“I was confused because I didn’t think I’d done anything wrong,” she said.
“I was shocked that they would report me but at that point I wasn’t worried because I thought the FA would have some common sense and not go through with [it].”
But Vaughan was then charged by Lancashire FA with “using abusive and/or indecent and/or insulting words or behaviour”.
It was further alleged it was an aggravated breach of FA rules because it included a reference to gender reassignment. According to documents seen by the BBC, Vaughan was alleged to have said, “that’s a man”, “are you a man” and “don’t come here again”, or similar.
Vaughan denied the charges, insisting that she did not intend to be offensive to her opponent or to challenge their chosen identity, but wanted to understand if the rules were being followed.
However, after a hearing, the disciplinary commission upheld both charges, finding that by raising the issue with the referee, Vaughan had showed a “continual action which indicated more than a casual question of curiosity.”
She was banned from all football for six matches, four of which were suspended for a period of one year, and was ordered to complete an online equality and diversity course.
“I was really upset,” said Vaughan. “It got put on my record that I’d been accused of misconduct, and I didn’t want that to stay there, and I knew I wasn’t guilty so I appealed it.”
In November, the matter was raised in parliament by former FA chairman Lord Triesman, who criticised the governing body’s handling of the case, saying Vaughan “seems to me to have been treated in a shabby way”, and her appeal was supported by campaign group the Free Speech Union.
The controversy also led to a protest by women’s rights campaigners outside Wembley before an England men’s fixture.
“It was really nice to see other people weren’t afraid to speak up,” said Vaughan.
