Perth couple Matt and Kim are prepared for another social media backlash after again being portrayed as villains on The Block Sky High.

They've already had one run-in on the Nine Network series, and the latest controversy, which erupted Monday night, will not make their lives any easier.

I am sick of being bullied and I'm a bit pissed off how they're doing this. 

On Monday night Matt and Kim were seen as double-crossing Trixie and Johnno following a pact to give each other 10 points for assessing each other's dining and living room renovations.

However, Matt and Kim only awarded Trixie and Johnno, who had stayed true to their word, a score of 9.5.

Matt denied on camera any such deal, while at the same time he was texting Trixie and Johnno to adjust their scores down by half a point.

In the end, Matt and Kim lifted their score to a perfect 10 to avoid controversy but the secret deal, which was not so secret on camera, blew up in Matt and Kim's face.

Matt told AAP he initially denied the pact because it was only between the two couples and that he was made out to be a liar when he had the interests of Trixie and Johnno in mind.

"I am sick of being bullied and I'm a bit pissed off how they're doing this," Matt said.

"It was my understanding we were keeping it between us... so I kept denying it.

"Then I found out Trixie had told the producers, so they have enough footage to make me look like we rigged the scores and it is taking all the credit out of our win."

Although it was Matt and Kim's first "room reveal" win, Matt is bracing himself for a Twitter and Facebook storm of comments.

Because the pair live in Perth, Matt said social comments start flying around well before the episode screens in their home town and well before they have seen the show.

"When something negative happens they (social media) are quite critical, that's representative of Australian culture - they like to hate," Matt said.

"The episodes where there are no problems we get no tweets, but when there is the slightest drama we get absolutely hammered with tweets."
