I can't believe how gullible you people are. Some random guy comes along asking for free thanks because you think he'll make a grenade hack is just plain stupid. Nobody has even seen or made a grenade hack in this game before, not even the "00b3r pr0 c0d3r5!!111". What makes you think he can do it?
Remove your thanks and give it back to him when he releases it and is proven to be fully working.
