There are a huge number of subdomains, used here, some link to specific related reviews, others to the main index page.

Is this SE spam?

It's a bit spammy to me (using 6000+ subdomains and 5 similar review pages that ranks for sitenames) but unfortunately, almost every page indexed from that domain has useful content on it so I'd call it aggressive SE optimization (instead of spam) combined with unique content..which is probably how any multi-paged site should be designed.
