So Scary... T.T

Well, playing about two years now, I've heard a great many different rumors.
Putting them together...
For one, a while ago, if you get chatted, you get hacked.
I associated that with him trading me twice to get my info.
In the guild hack, the person must force their way into the guild.
The buddy requests made it seem as if he was trying to force his way onto my buddy list, or make me DC since he's already traded me twice.

There's a thing under Game Option where you can block Buddy List invitations.

Eh? I don't see it.
You can block...

Whispers
Buddy Chat
Guild Chat
Chat Invite
Trade Requests
Party Requests
Guild Invites
Guild Alliance Tournaments <~ Whatever that is
Game Invites <~ Whatever that is

I don't see the icon to block buddy requests.
