but is it possible that the programmers of the second life do not understand that the block they have done is useless? that is, what is the purpose of a block if the blocker can still see and even be pushed by the avatar of the locked one? The block must be complete! this means that when one blocks the other regardless of who does it, both no longer have to see each other! and interact in any way, including the avatar, only this can guarantee true security! So we solve this problem because it is a very serious cause that ruins the safety of users and makes them move away from the second life.
