I am answering this anonymously, also for obvious reasons. As a referee, I get quite annoyed when, after having recommended rejection for a paper, and given several detailed reasons for the rejection, the same paper comes back to me from a different journal with no changes at all. In other words, the authors didn't even try to address my objections. In this case, I have absolutely no qualms about rejecting it all over again. On the other hand, if the authors genuinely tried to answer your objections, and you still think it is not acceptable in the new journal, maybe you should ask the editor to send it to a different referee.
