Name changed at 1,158 posts. Title was not changed, as I cannot verify the post count you had whenever Arun changed it. Thus cannot be sure you meet the 500 post minimum in b/w title changes.
If your VMs are correct, it was around 700 posts, but since there's no actual proof, so I cannot say for sure. Even if it was around 700 posts you have yet to reach the 500 post min in b/w changes.
