Under the Indian Penal Code (IPC), any act where an individual monitors the use by another person of the internet, email, or any other form of electronic communication is classified as the offense of stalking.
This specific action falls under Section 354D of the IPC, which deals with stalking.
Stalking is defined as repeatedly following, contacting, or attempting to contact a person despite clear indication of disinterest, and includes monitoring the person's online behavior.
Thus, for the given question, the man committing this act against a woman is guilty of the offense of stalking under the IPC.
