(ASK) About Negative SEO Attack and Redirect 301

I have 9 month blog (general niche/local language)

About two months ago I got negative SEO attack (404 page),
3000+ spam link with adult tags.


All the "adult link" is added after my domain url.
example:
mydomain[dot]com/tags/p**n
mydomain[dot]com/tags/S**

etc.



After that I use redirect plugin, and redirect all the 404 to blank post. And the problem gone

But few weeks later, google fret coming. (I got massive drop hit, from 7000pv/day to 1500pv/day.

I didn't do anything like 2 weeks, but didn't saw any increase in traffic
--------------------------------------------------------------------------------------------------
After 2 weeks I decide to dissavow some "suspicious link".

but after 3 weeks my pv drop even more, like 700pv/day
---------------------------------------------------------------------------------------------------
I try post new article that contain low competion keyword. And the result is teribble.
My article didn't even appears in google serp if I just write the keyword
(It appears when I type 'keyword' site:mydomain[dot.com])

It really weird, because before this, when I post new article, they always appears on page 2-5.
---------------------------------------------------------------------------------------------------
Today, I checked my GSC again and got "adult link" again.


It confused me,
Are google fred update or adult link that make my site drop?
---------------------------------------------------------------------------------------------------

If I redirect 301 my current domain to my clean new domain or clean aged domain. Will all bad link transfered too? Are there any better solution?

Are you sure this is not a malware attack and just 404 spam attack? Like something in your web hosting? Like a theme or plugin? Never heard of an attack like this actually working.

You can try this,

Remove your bad links.

Make fresh and quality contents

And redirect them you can start it as fresh you will get good traffic and views.
