All these sites are manly "who is", "about us", "website statistic", etc type of services, resulting in about 200 different pages with backlinks pointing back to your site. Some of them are no-follow and some are do-follow, but bottom line is that these are well established websites regularly crawled by Google and other SE, so your pages and backlinks on those websites will be found and your site will get backlinks and will be visited and indexed.
Thank you.....
