Aroa..
The NDA is Non-Disclosure Agreement
Which most places have people sign in which what they Might see/hear/read that they can not go around talking about.
So in other words, or an example Supposedly if the GM's have notes and say's Watch player X possible speed hack or X for Aim botting...
Knowing that, The GM's whom all have signed the NDA are not allowed to say anything to anyone Except other GM's, about it, like warn the person they are being watched
and or alert the person(s) who could be under investigation.
Even if the GM's hear or are given a briefing on what's coming up event, or whatever, they are not supposed to disclose any information to anyone else told to do so by the Senior
GM or the GM Supervisors..
Also..
You mentioned you are or have English as a 2nd language. Well you still could of Applied just to say, because knowing English is Great, but if per say you are Spanish, Brazilian, German or some other
language as your Natural Tongue actually can bean asset actually because if they took English Only and no one has a 2nd Language, moderating the chat can get pretty hard if know one
about can read German per say, and therefore how can you moderate the chat, having people who as I stated Have a Different 1st Language not of English, is actually an asset.
Since then you can moderate the chat If people are or start to talk in Your Native Language.
So, just because you say your not good in English, don't let that stop you if you do have a 2 or 3 other languages you can read/write or understand, thats a Bonus..
