Perderabo,
Of course, these were some what sarcastic webnames... hehehe...
If that is the case then UNIXForum.com/net/org or UnixTalk.com/net/org should pass the test.
If unixreview.com and unixusers.com, unixtopics.com and unixforum.com aren't the same usage and equally allowable under the portion you quoted, then I don't know who can dilineate the differnce. Or what, if any, use of the work UNIX in any website can be safe from this ruling.
These sure sound like examples of unix as the adj. modifing the noun. Maybe I am wrong, but I don't think so.
