I have a website in the quotes niche targeting very high volume, low competition and low cpc keywords (Majority Indian traffic). It is over 6 months old and was getting over 20k visits per day(though I was earning very less). A couple of weeks back I saw a drop on few keyword positions and thought it is normal. I checked up with ahrefs to see if everything was fine. Everything seemed normal. Then I took a look at the search console. There I found that there are over 34k backlinks from a single chinese domain. There were a few porn sites too. When I visited the urls specified in search console, there were no links to my website. I don't know how it is possible. I searched the internet and found that many big websites like searchenginejournal, seoroundtable claim that negative seo is a thing of the past. I have disavowed the entire domain(including the porn sites) but search console is still indexing new links from that same chinese domain and my rankings are still dropping. Please suggest on if negative seo is still a thing? If yes then recommend someone who can clean up this mess. A snapshot from my search console.
