@aakk9999 so are you saying neg seo exists or doesn't? Reading what you said it could go either way.
Google looks for patterns I agree. Who puts those patterns in place is what Google can't workout.
Now we have disavow tool. Which is great for people like us SEO's. Nearly every request I have had lately has been about help with the disavow tool. About 8 out of every 10!
But this is awful for webmasters who have no idea about SEO.
They have to now become amateur SEOs or hire an SEO to try and work out what backlinks are bad etc.
Most people on this site will work it out but the people I feel sorry for are those who don't even know sites like this exist.
