That is a good strategy, however, any new investor dropping in to "take a look- see" doesn't get your filter and might be under the assumption that a pure basher has some merit, and thus shy away from considering the investment, thinking the indictment of managment had some merit, even though it doesn't.
I say we have only one or two rebuttals to a pure bash and then a slew of green thumbs up endorsing the rebuttals to indicate to new investors the prevailing board opinion....because every board has their nut jobs....but newbies might not know it on a first glance.
