Just based on brazil84's karma total, the 150 number seems unlikely to be more than 50% of brazil84's posts. It seems very much within the margin of statistical error that there would be a number that high, especially given the other users with large numbers of downvotes against brazil84. I think reversing the votes on this amount of evidence would be a pretty big stretch, fwiw (despite being strongly in favor of the earlier ban as well as reversing all of Eugine's votes).
