A while ago a scholar who I don't know personally but I had read their work with interest (pretty big in Victorian lit, former Head of Dept etc) friended me on facebook - it was a bit surprising but I do use it a lot for networking and I could see he knew lots of friends of friends. Then he sent me several messages about how life has taken a difficult turn for him since he retired, and now he regularly asks me for money, with heart-rending stories each time. I can see other academic friends are sending him money on his fund raising platform. I feel really bad for him, but he's asking me so often. I am beginning to think he must have some sort of addiction. Has anyone encountered anything like this?
