This kind of website does not have a URL for every piece of information: it has a public URL for every potential piece of information, and it expects those to show up in search results. This would be similar to having every combination of words show up in your search results as a blank page on Wikipedia that you can edit to add content. When I use Google to find content, I want to find actual content, not ten billion placeholders: if the site doesn't have information on a particular phone number it should return a 404, not a 200, and not be indexed; there should then be a way to submit information into the database (actual information, not something totally useless like "reported") that then creates that URL. From the home page (which hopefully at this point has high page rank for being a non-spammy resource) they then should link to a list of "updates", which will be seen to change often, and the links on the other end of those will also change often, so Google will pick up new content quickly and efficiently. Yes: I realize that these websites are trying to rely on the search query as their discovery tool to get people to add content, and so doing this "harms" them, but if every one of them does this it becomes a useless discovery tool anyway (as the page of results is just pages and pages of these placeholders); imagine if every wiki did this: chaos.
