When he was posting as the 12-year-old he made some outrageously sexual posts. (Well, maybe only one, but it was bad.)
This was before I realized it was the middle-aged man posing as a child and as the child's great-grandmother. Supposedly it was the great-grandmother's account and the child was only online with her supervision so I sent "her" a note and "she" reamed me for being narrow-minded about her bright, healthy 12-year-old's openness about sexual matters.
I just checked his feedback. No negatives yet. I kinda would have expected some already if only because of the mint 9.9 descriptions turning out not to be true. So far so good though. Maybe you'll still get the marble if you still want it.
Did he really give you a tracking number?
