Someone called me?

In all seriousness I think many new users either skip over the faq, or see how much other people get when they're upvoted, and try to blanket the website with comments in an attempt to get upvotes. I think by design the time spent posting in every thread possible is worthwhile for some to try and snag a few pennies worth, and if punishing such posts actually costs something to do then it will rarely happen. Also I suspect that perhaps due to which languages are spoken by high powered users then there are many who are unable to communicate in their native language in any threads that would be economically worthwhile, and so the quality of their post simply cannot be that high because it is not their primary language.
