Yes, this should be table stakes for a classifier - a company with the resource of Google can definitely solve that problem if they weren't themselves in the business of spam (advertising) and benefited from spam sites (as they often include Google ads/analytics).
Always “table stakes”. Do you think in buzzwords also? I’ve always wondered this. Or do you think normal words and then translate it into this bandwagoning / membership proving garbage ?
We eventually have to ban accounts that post like this, so if you'd please stop doing that, we'd appreciate it. On HN the idea is: if you have a substantive point, make it thoughtfully; if not, please don't comment until you do.
