OK. This is my hypotheses... want the community to validate this. I may be on to something... Google released Penguin 1.0 knowing it would do collateral damage. They then released the Disavow Tool as a (false hope and lifeline to the SEOs industry) only with ONE main intention. And, that ONE intention was to get huge amounts of humanly crowdsourced manual link spam data so they could feed it into RankBrain as its seed data. RankBrain needed this "clean and atural" seed data of spammy link profiles so it could be trained via its deep learning mechanism. Why train RankBrain? So that it could eventually work with Penguin 4.0 to help and make it (run in) real time. Basically, I think Google played us. Assholes. Deliberately releasing Penguin 1.0 knowing it would be imperfect and torch a TON of sites and livelihoods. Then pretending to throw a lifeline they called the Disavow Tool (that never really worked or helped unless you also deleted links at the same time). And then used that crowdsourced data that we SEOs toiled to compile and sent them... to get to Penguin 4 Real Time so, the Penguin detected sites (too many toxic backlinks and onpage over-optimization) - could get bubbled up to the manual review team with higher accuracy AND speed. Jerks. I've written about this at length here IF anyone is remotely interested. But, I would appreciate comments from you guys AND specifically the experts here. This is not about ranking shit. I'm just talking about how they're moving to where they wanted to to take us down faster than before. Appreciate comments.
