After realising she'd deleted the comment, the user's sister wrote: "How come you blocked my sister after she raised the question as to your involvement in charity?
"As a public figure, you're supposed to be a role model to young women, spending what must have been 10s of thousands on lavish parties that you could have easily organised to raise awareness and funds for charity (and had equally as much fun).
"There is little if any attempt at raising charitable awareness on your social media. You have the power to share messages and awareness but instead, you block someone who questions why you don't?"
Moments after they shared their thoughts, they were also blocked and the comment was deleted.
Although Bec has been raving about her lavish party — with stars like Olivia Anderson, Nadia Bartel and Lana Wilkinson in attendance— she revealed yesterday that it wasn't all smooth sailing.
According to the popular influencer, their event was interrupted by police officers who turned up to her $7.3 million property in Brighton, Melbourne, after a neighbour lodged a complaint.
"At 4:40pm we have the police at the front door because a neighbour had complained because their daughter was trying to study and couldn't. 4:40pm on a Saturday afternoon. Unbelievable! The sun was shining, it was a beautiful day. Day, not night," she said on her KIIS FM radio show,The 3pm Pick-Up.
"Anyway, the police come. They take a listen and say, 'You can actually turn it up louder and you can actually go on later. You can go until 10:30.'"
Their presence came as a shock to the television presenter— who's married to AFL star Chris Judd— considering she'd warned her neighbours in advance that she and her husband were throwing a Coachella themed party.
"I am a bit of a goody-two-shoes and always make sure that I do the right thing by everybody," she added. "So I texted some of my neighbours, emailed some of the others and did a letter drop as well to all of the aforementioned people and said, 'It is going to be very loud. We have a DJ and a sax player, but it's going to finish at 10pm.'"
