Yes, if you are just starting out with a new search engine. But Google has 10+ years of data/experience to know at least which (types of) sites they want to suppress. They may not necessarily know which of the first 10 URLs that made the top cut should be #1 since they are supposedly all good pages but to intentionally let scrapers/spam in just to stir things up - that's a stretch. I see how an intentional SERP agitation could be useful to them but not outside the small range around the SERP that the page is ranked for by the algo.
It's tough to tell what's 'better' or 'worse' without a comparison, isn't it?
By "algo" I mean the total sum of all the ranking factors at play for the particular search which of course in different combinations can still be responsible for + or - 10 positions on top of the alleged intentional SERP flux.
