To be sure, the owner of a literary work has the right to prevent others from copying it and to profit from its use. The usual mechanism of redress is a cease-and-desist letter. Someone who wanted to make money from a literary work might even offer to license it for a fee commensurate with its worth. Sending a threat of lawsuit and a demand for thousands in "damages" to the recently bereaved strikes me as legal thuggery. Ellis reportedly claims copyright in her threatening letters, too, and threatens people who might want to call her out by posting the letters on line. She reportedly attempts to make a confidentiality agreement part of any settlement, possibly to keep word of her thuggery from getting around. If this has gotten you steamed up and you want to know more, you can find it here and here and here. In any case, you should never, ever use The Dash for anything.
With that introduction, I present a different poem, The Rash, by The Poet Laurie Atknott and reproduced here by permission of the author.
The RashFor it matters not, if this verse rhymes
Or whether the metre fits
Simply by perusing these lines
You'll soon be in the shit
Your loved one's dead; you waved goodbye
With verses that seemed right
Please pay the invoice I'll supply
All legal and polite
After all, we've just one life
And I really need the cash
The problem causing me some strife
Is a nasty little rash...
