In an ideal world, the forum software would automagically differentiate the crap from the contributions - 'knowledge leechers' from those who genuinely return the investment and try and add to the knowledge base. It would be intelligent enough to recognize which double-posts were valuable (for instance, new info about a program, or bumping a technical thread with new discoveries) and which were patently not. It would take an immediate distrust of those who came in asking yet again about DERP OF CERBERUS and that godawful compilation, put txt spk users on its watchlist and imprison Akari, offering him morsels of food in return for more wiki data. Alas, my AI still needs work (it's around 80% complete), so we'll just have to compromise.
What do I have in mind? Well, I think making unrelated a no-count board is an excellent idea. If Sl1982 is correct in suspecting it's mostly +1ing, it'll stop it dead in its tracks; if Kudistos Megistos is right that postcount has nothing to do with it, then there's no harm done, and a great way for us to differentiate technical contributors from those who use Qhimm as their own personal blogs.
