I think you're making an enormous intellectual leap from the data you have (someone with greater than 500 karma clicked a glyph of an inverted pyramid).
api's answer is the most complete response to the question so far.
Not really, api's comment is currently one of the last in this thread, which means that it has a low karma. On the other hand, it is likely that several people upvoted it - I did, and probably people who complain that it was downvoted also upvoted it, which means that it got several downvote - something not attributable to bad luck.
When I made that comment, there were 3 others in the thread. Next time I'll put a timestamp to add context (I'm not being sarcastic, I genuinely recognized the ambiguity)
