The issue of 2012 was more that the bad players all dropped off after the DOJ crackdown on online poker in 2011. It was still possible to play, but it became a pain in the ass to move money on and off the sites. That meant all the very casual players just didn't bother, and those were the ones you were making money from.

I played very successfully from 2005-2009, and I tried a couple of times post-2011 - it was just devoid of the total idiots that would feed you money.
