Legal issues can demolish a website so all work done on it will be nullified.Even if you get approved for adsense, it will cause legal issues in future.
>You can use a trademark(TM) name with good traffic google may or may not approve.Even If they approve it will cause issues in the future.This is not a worthy business and you won't get a profit.I have a domain with trademark in its name. It is like [TM]Help.com so for e.g. you can say OracleHelp.com.
If I create a blog on this domain and then apply for AdSense, do you think Google will approve? Or they never approve any website having TM name?
