Hi,
I am new here so if I am posting this in the wrong place, my apologies.
I have noticed a large number of people, mostly with fake accounts, posting on Facebook groups about helping link blockchain accounts to some Antminer S9 slots. They say they will do it for free but you need minimum investment in your blockchain account to start mining bitcoins. They promise thousands of dollars in a week period. some of them they promise 10 times your investment in 24hr. The whole setup sounds too good to be true. Anyone has experience with this or came across these posts?

Thanks.
