Ethics are rules of conduct or societal norms with respect to a group or culture.
An example of an unethically written article is a tabloid article titled Scary Pics Spark New Fears for Matthew Perry. The picures in it seem to be taken without the actor's consent, and the article uses false light, as it's based on conjecture. We do not know all the details of what is actually going on, and the article does not provide much information at all.
An article that was written ethically is one titled Prairie Patch Farm Llamas Become Destination Through TikTok Videos. It interviews the owner of the farm, so she is fully aware the article is being written and that pictures of the llamas are being taken. It goes into detail on subjects, and doesn't make up facts or conjecture.
