For Dummies Lawsuit?

I just registered a KWfordummies.com and then quickly realized that I probably made a mistake. I did research and found out that the For Dummies company aggressively attacks anyone that uses the For Dummies trademark.

However, I did find other sites out there that are KWfordummies.com and they are operating without a hitch. My domain will be a huge market even though it is just getting hot right now and I do want to build it out.

Any experts that can chime in? Thanks.
