While I cannot totally rule out the possibility, I have not witnessed as much as that not only on BMF.io, but even on other forums. The highest I have seen here is $150. There are many reasons for this. The system only allows hourly posting. And the highest that can be made per house $0.60. Practically, it will be difficult to make as much as $1000 in a month. Do you think it is possible to make such an amount?
