The anecdote at the start of the story seems off-target since that scam-artist wasn't an "imposter" of the sort discussed in "imposter syndrome".
To compare:
* Imposter-syndrome is when someone worries that they're incompetent/unworthy/whatever, when others probably wouldn't agree. They feel like others would look down upon them if (what they believe to be) the truth of their incompetence/unworthiness were to be revealed.
* An actual imposter would be someone actually incompetent. For example, someone who got hired to a role that they're actually bad at, but their incompetence hasn't been realized yet.
* The scam-artist discussed at the start of the story seems to have been more malicious than incompetent. While this would make them an "imposter" in a sense, it's not really what "imposter syndrome" is about.
