Rank KW that is not in Google Kw Planner

Hi I am interested in building some nich / micro niche sites. I was lookin for cheat and hack niche but I noticed that anything with cheat or hack is not listed in Google keyword planner. But was looking on spyfu and search volume was there.

Now my question is it possible to Rank keywords with cheat or hack in the key phrase on Google?

Will the site get approved by Google Adsense?

Hope you can help me and give me some advices or tips.
