Nostalrius Begins - Quality wow vanilla realm (1.12)

Dear GM
I have played WoW more then 8 years and i love vanilla as the best patch ever. It's very important for me to follow all your traditions and rulles. I have a hunter (Prapor) 60 lvl (MC/ZG geared), so there isn't any reasons to abuse your rules.
8.12.2015 i was in ZG raid with my guild "Blade of Darkness". There was all right. I didn't loot anything. After that i played few BGs.
9.12.2015 today i cant join the game becouse "This accound has beed closed".
I cant understand the reasone of it. I have never done any gold operations, bug killings of bosses, afk on BGs etc...
Please help me
Thank you!

Well, thank you for the answer. However it seems to be a mistake here. Could you check once more please? Or send me any proves of my cheating.

Look, I was playing in a good guild, well geared and had plans to continue a fair game in the future. I just don't understand how you decided that I'm trading gold....I had 100 gold only in my backpack.

As far as I know accounts with 1st lvl chars are doing this kind of stuff... It's not logical and increadibly risky for pers like mine. My motivation is comletely different.

Probably, I can prove it somehow, just let me know what should I do...

Thanks in advance for the answer
