I had a buyer who wanted an article akin to a very popular website where getting published is a big deal. The buyer wanted me to write it according to their guidelines. This was in the guidelines:
“Work you didn’t write is not acceptable. Warmed over posts (something you published previously with just a few new tweaks added) are also unacceptable. (Know that we usually spot these, and they make us very, very unhappy).”
I turned it down.
Why? Won’t that catch up to you? Seems highly unethical when it is in the terms you have to write it.
