If someone was mean to me in elementary school, I cannot just go and punch them in the face in the middle of the street today.

You can simply communicate with user in question or simply report them again if it continues.

What kind of comparison is that? this aint a years gap, it's two friggin months. That's not long.

And besides, It shouldn't matter how long it was. If someone was being an asshole, they're being an asshole, and should be disciplined for it. You're letting them get away with it.
