"Here's the thing though, it's not about Dom, it's not about Chrystal, it's about us, you and I - what are we doing? Have you read what these people are saying, the comments? For the love of God, it is just cruel, it is just unkind.
"Let's all just step back from the keyboard shall we? Stop being arsey, and just enjoy life and be kind."
Chrystal shared the video on her Facebook page, where she had earlier posted about how she was "just a Kiwi girl that didn't ask for all this".
"I didn't expect to be bullied online for my every move," she said.
"I danced my heart out for my partner Johnny, my charity and for everyone else at home. This kind of behaviour is unacceptable and until we change our stance on it, this cruel behaviour will remain.
"I have nothing more to say on the matter, but this attention was not wanted and this public situation sucks #sorrybutweknowyouarenotsorry.
"And we are all meant to be celebrating..... Congratulations Simon and Vanessa on your win!"
Family defends Harvey
Harvey's family has stepped into the row, telling the "haters" to "piss off".
His wife and co-host Jay Jay Harvey posted a heartfelt message on Facebook yesterday in his defence, saying "his main aim in life is to make people laugh".
Almost 2500 people have commented on her post, including Dom's mother and brother who waded into the public row to defend him.
Dom's mother Susan Harvey said: "Thanks Jay Jay for loving my Wonderful Son! As you know he is the best a son can be and I love him dearly and will always support him. Xox"
Her post was liked 1439 times this morning.
Dom's brother Daniel Harvey quickly joined the fray, telling his mum to "be very proud".
"He is the best son and sibling anyone could ever wish for. And to all the haters... Unless you know him, piss off. Don't comment on what you don't know!!!"
In response, Mrs Harvey said: "Daniel Harvey, love you so much and thanks for your support, I have raised four amazing children one of them Dom Harvey. You said exactly what I wanted to say! You are so right Dan he is a very loyal and supportive Husband, Son, Dad, Brother and Uncle, we love Dom Harvey xox"
Daniel Harvey replied: "Yeah we do...I am really f***ing annoyed about this because ppl don't know what an amazing person he is...I could not be prouder of a brother than what I am of him..."
Commenters on the Facebook page were split in support of Jay Jay and Dom, or for Chrystal, with many comments turning nasty towards the former Bachelor contestant.
