With every low quality site doing it for the past 20 years SEO hacking has become a thing, how can it still be so valuable?
How's it possible the Google algorithm changes against spam and extreme competition haven't driven this figure way down?
Google is still mostly relying on links, that's precisely why they're still so SEO-hackable after SEOs doing it for two decades: they have no other mechanisms. $150 is totally worth it.
As a result this is not money for OSS at all.
Edit: nevermind, I mixed it up with rel="nofollow" which would be worthless to spammers.
