Garbage in, garbage out.  If returning one particular kind of garbage
to one common client that sends garbage works, then this is what
people will do.  It doesn't violate technical DNS specifications,
since technical specifications by definition cannot regulate things
that isn't part of the protocol.  It may violate an operational DNS
specification or BCP, but I'm not aware of such documents.
