Answer:
Paragraph 5 details about the character of the person behind the "mask" who uses an internet persona.
Step-by-step explanation:
Online identity is regularly established by internet users who surf the internet. While some users explicitly divulge their personality, others are deceptive in their revelation. However, the proliferation of social media has made the notion of online persona quite complex since users seldom divulge their explicit profiles and choices.
Social media creates a “mask effect” which helps the user to masquerade behind its shadow. The genesis of masks can be varied but the common thing is people build up that “mask” following their choices and likes. Hence, if anyone wishes to study any person character, he can refer to his masks and extrapolate those observations over his character.
