actually no..
that target lock trick is not found out by him.
infact is another person whom found out then share the info to him via twitter or sth...
PN then share on his channel.. (becos his channel can garner more audience n awareness. If I'm not wrong.. that's what that person want - becos that person is just some very regular person with very little follower).
In the very early few video.. PN actually did mention that person and credit that person.
But seems like.. everyone tot that trick is found out by him.. which is not.
oh well. lucky him tho.. that person really his samaritan.. becos of this trick.. his channel grow bigger.
