I upvoted every answer - so 1,000 points. 41 of my answers got the achievement of "Great Answer", which was about 12,000 points, and another 12 got "Good Answer" which was about 2,000 points. That's already about 15,000 points.
And I posted 30 answers that just got deleted so I could have potentially gotten around 1,200 from answering points alone, and some from upvotes. So it is technically more than 15k.
