Actually I was disappointed by the post, I was hoping it will be able to find the same person regardless of the username through analyzing the writing style, what they are talking about, the timezone etc.
The username doesn't prove anything, anybody can take any username anywhere. If someone targets you, they can take usernames on platforms you haven't claimed your username yet and pretend being you and damage your reputation.
