Kentucky fans are not happy this week the Wildcats are home for the Final Four.

And they're largely placing blame on referee John Higgins, who was chastised throughout Sunday's game vs. North Carolina for several head-scratching whistles leading to fouls called against the Wildcats.

The vitriol has spread to Facebook, where Kentucky fans are spamming Higgins' roofing company, John Higgins Weatherguard Inc., with bad reviews and false claims.

A few examples of the slander:

"John personally came out to fix my roof," Melvin Matthew wrote on Higgins' company page. "I'll say this guy was very professional, he hit on my 13-year-old son and clogged my toilet and didn't tell anyone."

"I am very disappointed with the services of this roofing company," Patrick Price writes. "They were rude and slow. They also hired undocumented illegal aliens who stared at my daughter sunbathing the entire time they were working."

There are several other examples, including threats of physical violence. Higgins’ company has a 1.2 rating (out of five) on Facebook, which will lead to less reach and inevitably, revenue.

Despicable.

Here's what Kentucky coach John Calipari said about the officiating after Sunday's loss to North Carolina:

"You know, it's amazing that we were in that game where they practically fouled out my team. Amazing that we had a chance. So proud of how these guys fought."

Officials were chastised throughout the first half via social media before the conversation simmered a bit after intermission. The Wildcats held a 5-point lead with five minutes to play.
