FakeSpoilers-kun goes by many names (as he has many alts and never posts on OT with his main account) and has never actually been called FakeSpoilers-kun nor does anyone know he is the same person with each account.

He regularly posts fake spoilers (hence the name) for various weekly manga (and occasionally monthly ones) as well as posting the occasional flame war bait.

By the way, Uryu dies this week in Bleach.
