So it's a magic act. As a programmer, this frustrates me terribly. I just emailed dang yesterday because I had submitted something that shot up, got a lot of attention, then died just as suddenly. Hell, I didn't know, I thought the system was broken or something. Turns out I was flagged.
The upvote thing you mention is especially annoying. You click the little button, you're expecting something to happen. That's the nature of clicking little buttons on computer interfaces.
Hell-banning also drives me nuts, for similar reasons. Computers should serve us, not the other way around. [insert long discussion here about having to manage a site with a zillion users, and how it's easy for me to rant about this but I should walk a mile in dang's shoes, etc.]
