Thanks for reporting. Hopefully they will take action against these scammers. Nowadays fake giveaway websites are coming in large numbers, which is very dangerous for newcomers. The main reason for these websites to come is the rising price of Bitcoin. We have seen before that when the price of Bitcoin goes up, the number of scammers increases. So now we have to be very careful.
So far no reply from Namesilo, I will make a follow up if they didn't reply or will try to find out who to escalate this kind of issues. Yes, I agree that this is really dangerous, specially that newbies just blindly believed everything they see specially earning very easy money. The attack became rampant because of the block halving itself.
