You shouldn't stop here to do your own research. Anyone and even a member with a good reputation can be fooled one day. You also need to learn how future project prospects are, even if you believe the project is safe from potential scams.
So far, Hhampuz hasn't stated that this is his project. I don't think Hhampuz will be fully responsible for your losses.
I seriously doubt this is Hhampuz project, maybe he will handle the promotional campaign for this project. Anyway, I don't think he will be liable for possible losses of an investor on this project if he is not in anyway part of the team. It is always the user's responsibility to do his own due diligence when it comes to investing in crypto project. He can't do the work for you.
