Ignore function is effective at one (1x1) level. One must decide to do virtual (silent) or real (other). So, the balance will establish itself after some time. My sense is, that has happened here and I agree. But, many here do add value-insights-knowledge w/o constantly being critical.
It is easy to spot the "always negative" posts. If MODS keep an eye on # or % of IGNORE votes and do the math it might help. IMO.
