I emailed my college academic adviser at 3:30 in the morning, what will she assume of me? That I'm an party animal? A crazed insomniac?

This person posts continual pro child molestation questions over and over. When confronted he claims that it's just him joking around. It might be true if he only did it one time, but he does it over and over again. This indicates that he is indulging a fantasy and getting off on imagining himself doing this. Reporting him to Yahoo does no good at all so I encourage everyone to report him on either or both of the following links as a suspected child predator.

Could be any number of things including but not limited to:

Being anxious

Night owl

nerves

Probably a poor sleep deprived college student
