[ANSWERED]Banned for using /gc command

[Ellvo]

As topic says I've just get banned on start of heroic raid toc inside (raid didnt start we've been waiting for players to come in)
and I've used /gc/gs (gear score command that pops up) on friend's character, suddenly I've get instant ban for ninja something.
Can I get some explanation what is that and hopefuly get fast unban as far I did nothing :O ?
