Strategy to get subscribers to your channel free

As you saw in the title, today I'll show you a strategy to have subscribers to our channels without paying any thing (100% free) .
The strategy is to join a group in facebook where we gonna invite people to subscribe in each channel you want.
So Join this group then each one of us gonna add his own friends, then everyday I'll post 5 channel links, and each one of members have to subscribe on them without exceptions.
We gonna choose 5 channel by order by time.
So if you are interested you have just to join the group
This is the group name: "get free youtube subscribers freee", it have a an icon like "lamp".

do you have a plan to hide the referrer so youtube doesn't see all these subs coming from a few fb groups?

Don't worry about that!
We will told all subscribers to search the channel in youtube, watch one video then subscribe.
