I was checking backlink profile of some sites on ahrefs and found this on Xtremetricks.net

I posted it to remind all of you guys to check your search console every day. I recently show many guys facing negative SEO attacks.
@Xaif Do you know it already?
Yes, I know this already. I have already removed those links in June.
