Say you found out that the keyword "youtub" is getting millions of searches a year. It's pretty obvious that these searches are just misspellings of the company Youtube. You decide you want to try to capitalize on this misspelling by creating a "single person bathtub" product and calling it the "You Tub" and registering "theyoutub.com" domain.
Would Youtube have any sort of trademark/copyright claim on "You Tub"? Would they be able to seize your domain for squatting or similar issues?
On one hand the product is in a completely diffrent non-competing industry, there are no claims of affiliation or trying to phish or trick the user once on the page, and the brand name is relevant to the product. But on the other hand I think most people could see the goal here was to try to gain traffic that was meant for Youtube.
