i think it's one of those idea that sound good but won't do anything? Let's say you manage to do it, what would be the point of having 1 page with 1 mil likes and 0 interaction, as you will have no reach, no interaction because all the likes are quite fake. Also 1 mil pages sound good in theory, but that's a lot, you will need a serious bot that will be able to even come close of trying to do that, not to mention that fb might also have limits in place from stopping people to do this
