I've just looked at the stats for a relatively new member and cannot believe the rep he supposedly made in one day, being a relative rookie. https://stackoverflow.com/users/2125720/jayram?tab=reputation
Can this accumulation of rep for June 11 be explained? Was there something going on in the back end?
I posted a comment on one of his answers, which contained only links, advising that he should summarize the solution in the post, as per SO best practice. He replied with a very cocky "Sure ..." - Where/How did he get that many reputation in one day? Hard to believe it's not a system error.
