This is probably most useful for people who speak English as a second language trying to name something in English because it's de facto our current lingua franca and gets called globish for that reason.
I've given people on HN feedback a few times about how "that doesn't mean what you think it means and sounds to me like a terrible name for this project and here's why." A website checking for things like this is maybe a reasonable first step for some people, but if you aren't somewhat fluent in the culture and language of your primary target audience, a website like this is likely insufficient. You should get some "live" feedback as well if you aren't sure, preferably from someone like me who is prone to being too truthful to be good. People with better "manners" may not tell you honestly "Ha! That sounds like (offensive as all hell phrase) to me!"
