Maybe, for clarity, all adverts should, as the very first word, name the manufacturer of any given product. A Limelight would be listed as such and a no-name would also have to be so called. You might want to add that it carries a particular logo but that would be clear (and so would any intention to deceive by default) from any photos.
Maybe there should also be a rule that all items for sale have a front and back photo too. People only ask for them anyway.
