Fictional story
One day, Mr. Y wanted to register on the Poster website. To add comments, and generally use all the privileges of an insider.
On the site, Mr. Y saw the registration button: I

clicked on it, got a nice window, and began to enter my plain data. By the way, he decided to leave his own name with a password (in order to forget in the turmoil):

Mr. Y (unlike me) was not at all surprised when the system willingly let him in, not puzzled by the strangeness of the data:


Now Mr. Y calmly writes reviews, leaves comments and so on:

Something is wrong here, huh?
