We have a strict rule against unethical requests like ghost writing, plagiarism, study assignments etc. If you see this in a service request or conversation, tell us! We will close the request immediately. The Peerwith platform aims to connect researchers and experts to be able to collaborate for services like language editing, translations, data management etc. Peerwith does not support requests for unethical services and we will close requests which we feel are not following common ethical practices.
There are also less obvious cases like paraphrasing. What an expert does and does not, depends on best practices or personal preferences. There might be some discussion on the subject too, like here about paraphrasing, Glenna's opinion. Any doubt = out, so in case you see something that you consider unethical, tell us and we will respond promptly.
