Looks like it's only for the first 500 customers, and being registered in Australia, the website is almost certainly going to want you to complete KYC verification.
Sell my ID to some sketchy new website for $15? I think not.
Otherwise, simply sign up and withdraw the money, rince and repeat with muliple IP addresses.
I think that nowadays it doesn´t matter where you send your IDs. We have seen that our datas are not safe any more. I am talking about Facebook affair or last Binance KYC hack.

KYCs are not really much of a big deal anymore because hackers can get it even from third party kyc platforms or exchanges just like that of Binance hack few months ago. The most important factor should be doing your best to verify the platform you give it to. Besides, security operatives are now knowledgable of the rampant identity theft happening accross the globe so I doubt you will go to jail for having a random guy use your data to Rob a bank in Mexico while you are in South Africa
