I met a girl on an internet forum who expressed how she at 17 years old liked an older man (a 50 year old). As I am someone who had a similar experience (but I was an 18 year old woman, so legal) she asked me for advice on her situation.
I'm still hesitant as to whether I want to "help her out" or not since that could be considered grooming. Although I haven't given her any advice yet, I have advised her against some things. For example, she expressed how she wanted to wear something "sexy" to get his attention, to which I said that could be a bad idea. She also wants to hold off on anything until she turns 18, then ask him out. But I feel like even advising her from this frame could be illegal since it could seem like I'm encouraging her to pursue him.
To the extent of my knowledge he hadn't groomed her, since according to her she basically fancied him when she saw him for the first time. They met at a formal event and only engaged in small talk, he didn't flirt with her in any way. I would also like to add that I don't know her real life identity or where she's from, nor does she know mine, but her name sounds western.
