The activity allows the production of the writer’s profile (unknown subject) who carries out persecutory actions (sending anonymous letters) as well as providing predictions on:

• Educational level;
• Socio-cultural level;
• Analysis of the writer's cognitive level and emotional state by evaluating the terminology and graphic style (if it is handwritten) used;
• Significant probability regarding the writer's gender;
• Hypothesis on the possible motivations of the writer;
• Objective risk probability for the recipient of the letter.

This activity therefore has the purpose of restricting the possible circle of people and identifying the sender more easily.
