This label should be assigned when an account is pretending to be someone it is not.
Some imposter accounts are very convincing, using plausible handles, copying images, and writing like the author would. A casual browser of your collection might not notice the imposter, so it is good to label as such! These accounts may be bots, or may be real people.
A mask to hide the plant's true identity!
Smart people prove theories. Dumb people repeat them.
