No it is not cr*p because 1. Most airlines in AE (even non-spams) do it and 2. there are 168 hrs a week, so I still have 168-(19*7)=45 free hours technically LOL.
You do realize that 28 of those hours are for maintenance, right? Leaving your aircraft with a mere 17 hours free a week. This is one of the easier spammy things to fix in an airline, though. You can easily start a new airline and keep utilization low. You can also start shifting to realistic seat configurations while you're at it. (If your goal is to stop being called a spamline)
