Data Center Proxies vs Reseidential Proxies (blog.scrapinghub.com)

Given the topic of proxies plus "scraping" in the domain name, I was expecting more relevant information. For example: 1) techniques to avoid being blacklisted 2) some indication of cost factors. Not just the difference between residential and data center - but within data centers themselves.

I realize it's just a blog post, but I felt it was still rather shallow and non-informative.
