Not really, because if a node must be considered to be reaped, then there must be a valid reason to consider it. According to the current documentation on consideration (linked multiple times earlier in this thread), the kind of posts we're talking about don't qualify unless you consider them "offensive." (Being incorrect is specifically said not to be grounds for consideration.) They offend me, but the consensus seems to be that they aren't offensive, or at least not offensive enough to be censored like spam or porn.
