That was a dreadful hit piece. Salmond was found not guilty on 13 charges because he proved in court the alleged incidents didn't happen. Note how Wark's supposed day-by-day account of the trial skips over the two days when the defence witnesses testified.
This included the friend of the alleged victim of the worst charge telling the court that the incident could not have happened because the victim had asked her friend to attend the meal in her stead. (The victim had injured her arm on the day and stayed home).
On one charge it was a not proven verdict. Salmond agreed the incident happened. The question was whether it was a miscommunication between them that amounted to harassment. At the time the victim accepted his apology for him giving her a (fully clothed) cuddle when they were both drunk and she stated nothing untoward ever happened again afterwards.
(Not proven simply means that there was not enough evidence either way - neither the prosecution nor the defence could prove their case.)
Wark has a bit of a thing for Salmond. No idea if it's personal, but there have been a few other pieces she did about him that were less than balanced or impartial.
If you know anything about the case that becomes very obvious. Like the fact that Salmond presented a different defence case than the one he said he would is used to cast doubt on his character. The fact that he had to present a different defence case because the judge didn't allow him to present the evidence he had on his original defence case is not mentioned by Wark at all.
And so on.
