Whatever. Big G updates it algorithm constantly... We're talking at least several times a month. Panda was a bigger than normal change, but it was not a flipping game changer...
If you're not ranking well, look at those that are, see what they are doing and do something similar, or better yet, do that shit better... The best way to succeed is to emulate success, and then kick it in the balls with your own spin, but for Christ sake people stop blaming failure on some change to the search engines...
If the game changes then change your game... Don't fucking complain that somehow the rules played you when you're the black hat guy trying to play the rules... Adapt, figure out the new rules, find the flaw and make some money...
That is what Black Hat World, and being black hat is all about, adapt and survive, complain and starve, that's your choice...
