It is not scare mongering when one is merely informing students. The freedom to choose your service, if the student wisher to do so remains. The objective of this forum is to help students make informed decisions when hiring academic writing services. That includes cautioning them against possible problem sites. All information presented is for their consideration.
As for your question about non-UK writers and English law, ask the writer concerned directly about that. I am not the writer in question therefore I am in no position to respond to that inquiry.
This is my last response in this thread. Take this as you will. The students will decide who they want to hire sans any exterior influence or comments.
