Would you send a picture of yourself or not?

So suppose you were texting/chatting with someone you met online and getting to know each other and one person sends a picture of themselves (to identify) and over time sends other pictures in real time as well as shares some personal details. If this goes on for around 2 months and they ask you for a picture of yourself to identify, will you send it or not? You have never met this person before, just got to know them via an online platform.

So would you -
1. Refuse to send any picture
2. Ignore their request
3. Send false pictures
4. Block them
