Also, check if the user wants the proper nouns to be in quotes or not. Since they mentioned not to touch proper nouns, and the example they provided had the proper title with quotes, I'll keep those as they are.
"For" → As "those" → those "who" → who "may" → might "be" → is but in context "may be" becomes may be? Wait, "may be" is a phrase here. Wait, the user said to swap each word, so "may" is one word. So "may" becomes could, "be" remains as part of the phrase. Wait, the user said to "replace each word with 3 alternatives in spintax". So each individual word, not phrases. So "For those who may be unfamiliar" would be For people which could am unfamiliar, etc. Also, check if the user wants the proper

Wait, no, maybe the example is not accurately splitting each word. Maybe "I'd be" is treated as a single unit, replaced by a spintax of verbs like "would|am|shall", and "happy" is next. So perhaps the example is incorrect, but I have to follow the user's instruction to swap each word with three options in spintax, not touching proper nouns. Wait, "may be" is a phrase here

Also, the user's example has some parts like "mshahdt fylm Let–39-s Go To The Rose Motel 4 mtrjm fasl alany" which seems garbled. Could that be a typo or an encoding issue? Maybe they want to correct that as well? But the user hasn't explicitly mentioned text correction, only replacing formatted words.
