@HolgerN,

The method in the thread you posted is exactly the same one being used by the OP. Perhaps 127.0.0.1 will have other (also unintended) consequences as 0.0.0.0, but, at least in my book, it will be exactly as wrong as the other one.

Obviously many people use /etc/hosts for ad blocking, and I guess most live with it OK, but then they should not be surprised if something goes wrong, as the case is in this thread.
