My relatives are involved in a task scam but it’s very large scale so I can’t convince them

The company scamming them is this Cloudboost Technology Advertising Co Ltd. You can find them on google and even linkedin. It’s a normal task scam where you do tasks to earn money but in order to withdraw the money you have to buy packages. So far they have been able to withdraw over $3000 in this scam, but they did spend $3000 for the package. Since they are earning money its so hard to make them understand its a scam. There are 500 people in the whats app group that is part of this scam right now and it’s sad to see because I know half of them.

Even more crazy is that the company held a buffet event with hundreds of people making them seem legit. I don’t know when they wil get scammed but do yall think it will be all together, because they don’t seem to be scamming people one by one. It makes my heart sink
