Nobody can answer this question apart from the owner of that address because the security of it depends on how it was created. Although this may look odd to you but it is perfectly within the realm of possibility that this was created randomly and the owner may not even have realized its characteristics!

And how much have you searched for it? Randomly trying to generate a handful of addresses doesn't count though.

I'm too lazy to download, write some code and process 750 MB file but you can do it if you like from here: https://bitcointalk.org/index.php?topic=5254914.0 and see if your assessment was correct.
