If I have a subdomain that contains "bad" words will the search engines mark my domain and the rest of the subdomains as not "family friendly"? For example for words that aren't accepted by Google Adsense, will Google mark the whole domain as unfit for family search?
No, everything I've seen in my personal experience and have heard from top SEOs says that search engines treat sub domains as separate entities. If this wasn't the case, every Web 2.0 site that gives users subdomains (Wordpress, Blogger, ect) would have it's top domain affected by the content, backlinks of the sub domains.
That's why I asked because Blogger, Wordpress, etc home pages should have to suffer, but I was thinking that maybe they have something implemented in their subdomains or domain for search engines.
