The three-character disclosure that turns a post into an advert — #ad — adopted by influencers from about 2015, made mandatory in spirit by regulators in 2017, and placed, wherever possible, where nobody will see it. The record's entry for the smallest legal notice on the internet.
The record notes #ad has variants (#sp, #spon, #partner, #gifted) whose only purpose is to be less clear, and that regulators have said so in writing.
The record notes that 'ambassador' is not a disclosure, that 'collab' is not a disclosure, and that the FTC has a list.
What does it mean? Write it the way you would say it out loud.
