I've been paying attention the the questions raised and upvoted over the last few weekends, I don't have much of a sleeping pattern so I'm on at all kinds of times and I've noticed a distinct pattern as we move through the timezones.
At around 330/4am GMT, which corresponds to the start of the day in India many questions are raised which are either very poor quality (ie no research done by the poster and no attempt to even try themselves) or where no actual question is asked. These questions are then routinely upvoted, earning reputation, as are answers which offer no solution or are hugely wide of the mark.
Later in the day when much of Western Europe come online similar questions are downvoted (which I consider to be correct), but not only that many other very reasonable/fair questions are also routinely downvoted without explanation
Towards the end of my working day (around 1800 GMT) both the up and downvoting appear to balance out.
The problem has really stood out to me now the moderator voting is open - I viewed the required badges and it seems that many users have earned some of the badges plus many others such as 'famous question' without ever having posted a valid question and when providing no useful answers ever, so they have a good deal of reputation which doesn't reflect how they have acted on the exchange
Is there any thought being put into making this system fairer to account for these differences? For instance, when a question is flagged or reviewed, shouln't 'fraudulent' upvote reputation (where the question or answer clearly isn't valid) be negated?
Another reason I think this problem needs addressing is that on these badly upvoted questions downvotes will penalize the person doing the downvote - but still leave the poster of the bad question with an overall positive reputation gain.
