Hi guys I am looking for some advice.
One of my gigs is about selling Thai phrases with simple phonetic pronunciation guides for travelers to enhance their visit. I sold an article some time ago to a nice buyer who used my work on his website, it is still there as we speak. I now have a buyer asking for very similar work, which means I can simply tweak my old job. However, a plagiarism checker shows 100% plagiarized from his site, which is obviously my original work. The new buyer is amazing and I do not want to scare him away by making him think I have stolen this content, it is original content written by me.
What should I do about this?
