What do you usually do if someone you don’t know talks to you online?

If someone I don't know talks to me online, I would typically respond politely but cautiously. I may engage in conversation briefly to see what they want or what they are looking for, but I would not share any personal information or details about myself. If the person makes me feel uncomfortable or exhibits inappropriate behavior, I would block or ignore them. It's always important to prioritize your safety and boundaries when interacting with strangers online.
