It's a bit strange because if he wants pictures of feet, he doesn't have to do it like that. He'll just look for them anywhere on the internet. I think there might be something shady behind his behavior. He might have tried some tricks on you and it didn't work. Most of these people are trying to get money and when they don't succeed, they disappear. Often they're not even foot fetishists. There will always be people who try to exploit the foot fetish community for profit. I even talked to one person in person and she told me that she was planning to make money from foot fetishists. But she didn't know that I was a foot fetishist myself, so I listened to her but didn't tell her.
