I saw an example of this link removal urgency in someones mind result in going overboard. His site had recently 'cleaned up'. He complained it still isn't ranking (he didn't disclose his search KW's).
I got curious and checked his backlinks in ahrefs; so funny it was over cleaned to the max. All that was left was directories and forum signature links. Also not present: authority sites, niche orgs, CofC, local portals or other niche related (huge and highly competitive niche) sites!
Totally absent was any scrapers, pron sites, article boards, press releases and other questionable stuff G has devalued recently. Too funny....
