Did I get hacked or is this a glitch?

2 of my guildies also report this, one had her mule account cleared of everything on equips, but nothing in the other categories. The other just said his entire main char was cleared out, he did not specify what that meant though. Neither of those persons shared their accounts, and it happened this week for both.

I'm not saying its a glitch or exploit and that they are not to blame themselves, but it IS a possibility, so be careful.
