Every post on this forum is subject to + or - rep regardless of the age of the post.
I don't believe eejit101 went looking for something to give negative rep to.
Someone posted in the thread and it became a "new" thread as eejit101 was checking the forum.
He gave it negative rep and had I seen it the same way he did I would have given it negative rep as well.
