There's no need to get into trademarks etc as the content you're talking about isn't your name or logo, but rather the FAQ questions and answers that you wrote.
We're all benefiting from this discussion so we'll be following the outcomes and why or why not the strategies worked.
Are the FAQ questions/answers still under copyright or are they now considered "Public Domain". If they're in the latter aren't they free to use and can a DMCA request still be enforced? :dontknow:
