I don't see why this would be a problem. You wrote that all sites are informative.
I do because is just a doorway. You host 50 pages saying: "visit Xcity where you can see X thing blabla, and buy in spamsite"
50 times. There's no reason for the existance of 50 different domains. All they have to do is spamsite with all "informative" content for 50 cities.
But since they do have better chance to collect traffic, they build 50 "informative" sites of 5 pages each to point 1 site.
If you were DMOZ editor you would be sending it to spam as "DOORWAY".
Are you really serious when you say you find no problem in building 50 sites of 5 pages each to end saying "buy in spamsite" each time?
