I don't understand how marking all links as DEAD helps.  Presumably,
a site that's doing active rerouting is using pathalias data to do so.
Mail traveling through the rerouting site does so because:

	1. The originating site routed the mail using pathalias data,
	   in which case the route probably will not be altered by
	   the rerouting site.  DEAD has no beneficial effect.

	2. The mail was routed "manually" by a human that rightly or
	   wrongly knows a good route.  DEAD has no effect whatsoever
	   on manual routing.

Explanation?
