you need to provide a little bit more details here. coz I am smiling something fishy here. why do you want people to copy content from different sites? if you want to copy those articles and publish them on your own website then it is an illegal thing to do because it is against copyright laws.
but there can be other reasons too I heard some people take content from websites to train their AI models (don't know if that is legal or not tho) so you have to explain the purpose of this task.
