@renatovieira I think christianz was being a little sarcastic but not mean on purpose; we are all feeling it right now, and it is easy to get frustrated, but remember, we need to direct it at Google. I understand your frustration. It's a horrible time for everyone.
As for E-A-T, as I have said in previous posts, I got important backlinks naturally acquired from just having a good site. My DA hovers between 78 to 80 these days, yet crappy websites that manually steal my posts now outrank me since the October spam update. Before this, I had no issues since I would surpass them. Sometimes the original post is not even in the top 100. It is blacklisted, yet a copycat gets ranked 1 to 5 with my stolen content a week later, WTF Google?.
These crappy spam, blackhat, or just plain thieving sites have DA of 5 to, at best, 25, but have been doing this sort of crap to other people's sites before targeting mine due to the quality for like 5 to 10 years, but literally, some of these sites are 99% copied word for word. Also, all these sites in question have comments. I got heaps of comments and interactions, which shows, besides the authority with my high D.A., trustfulness since it's real communication with a community. Also, I add more details than anyone. I would add a competitor; in fact, my site grew since I added more images to explain to people that do not follow text; it takes me ages to take images and watermark them.
To me, this shows that E-A-T means nothing or it is broken. It shows that their spam filters are broken, do not identify so many sites we all see and know in our niches, and cannot remove the actual crud. At the same time, our websites get hit, showing Google's search team has no clue, has broken things, and does not have the ability, or even scarier, to understand what is going on. Listening to Podcasts, I laugh hard since it's, yeah, most of us know it's rubbish.
Or it's a broader conspiracy, tin-foil.
