I thought blogspam meant low-effort, SEO-optimized articles found on websites trying to sell you stuff. Small opinionated blog posts referring to other blogs are not really blogspam although I can see the comparison in an offhand sort of way.

I agree. Some people do great things with whatever they have on hands, and some... well... just whining.

This one adds another example of the distracting invasive mess that article doesn't have.
