Blocked for refusing to send a photo

I was inboxed by a woman 30 years my junior asking to be friends. I don't want to refuse anyone friendship so I accepted. She asked to talk on hangouts so I downloaded it to talk. Three days into the 'friendship' she asked me to send a photo. I wasn't comfortable with sending a young woman a photo of me so I asked her to wait a while. She immediately disappeared from chat and blocked me on SW.
I used to be on EP and made a couple of good friends there. Is this incarnation really so different?
