There are 17 comments on the article. 11 of them are spam comments.
I see this more and more on content sites. I assume they all are using various spam filtering systems. Yet the spammers win, again and again.
Is FB/Disqus the only answer?
As long as there's a profit margin, it will be automated or outsourced.
But, that's not to say the amount of spam can't be minimized. I can't say for sure, but it doesn't look like Wired has /any/ sort of spam prevention technology re: their article comment section. A tool such as Askimet (http://akismet.com/) can quell the amount of spam, but it won't eliminate it completely.
They seem to be losing on HN. Mostly because we're very low-profile, but for a while there were bunches of spam comments by new users. They all ended up dead really quickly, and it seems to have petered out (nothing in the first two pages of /noobcomments), though there are occasional bursts.
There are also all the spam articles (look at /noobstories), but again, most of those end up dead instantly, and the ones which don't never go anywhere. The fact that every link off-site has rel=nofollow probably helps - no link juice gets given to other sites, so spamming HN doesn't improve search rank. The hellbanning system probably helps too - if a spam account is banned, it doesn't notice anything different, but everything it submits is autokilled.
