Use wayback machine or web archive check how the website look like in past few years, you will know it was only a domain and bought recently although it was registered awhile ago.
Ask any domain buyers they will let u know, anyone can buy domain and park for re-sell.
For company being sold, go check ASIC registrar, the company recently had a change in board resolution, and change of entity names. Buy the records of the past versus current if you bother to dig.
ASIC is already notified of this company, and it is obviously breaching AML Law, so good luck.
