I just knew that yahoo server can make us unbootable, but, this trick not tested yet. I inquiring how some of yahoo server can be used as anti boot. I though that this is impossible or not logic. But it depend on the number of user use the yahoo server. If the user not quite enough or only few used that server may be its can be used to anti boot.
But I still do not know yet.
