Nope, not at all. Innocent until proven guilty, and so-called logs of AIM conversations are worthless.
Since I'm sure I'm about to get labeled a pedophile-supporter for my insistence that we wait and see the specifics (legitimacy of the AIM messages, what was actually said that was sexually explicit, etc.), I think now is a good time to check out some other threads and come back to this one when things have cooled down a bit. (Both on my end and others).
