...an irrlevant link from Harvard, is... just as irrelevant. uh, er, no, actually it's worse, for it'll flag you until you gather enough trust, relevance to counter that link... as if you could ...and the root of all -950 rankings. ...Irrelevant links ie. the *source* is NOT related to the *target* won't go nowhere + kill your rankings for life.

So a single irrelevant PR9 link can bomb a whole site unless that site has the equivalent in relevant links? It sounds like an easy way to sabotage a competitor.

Or do you mean many such links?

I was under the impression that dubious incoming links would only ever be devalued, rather than actually hurt a site.
