Chat ban for 10 years

Dear GM, i was trying to sell my Stronghold Gauntlets epic recipe on trade and world channel when i got chat ban! "You must wait 3471 days 10hours before speaking again" it says and i cant even wisper, so i cant communicate with anyone for like 10 years
Maybe the mistake i did is that i was writing exact the same message during this weak (but i never wrote it more than 1 time in each channel in a row) or because there was the word "gold" on it! "wts plans: stronghold gauntlets, get your gold maker recipe cheaper than AH", maybe a anti-spam system saw it like im trying to sell golds for money but i never did something like this for sure!
Its the third time im trying to make a topic about it but the previous 2 posts aren't on the forum, if im doing something wrong and mods dont approve it for that please send me a message
My character is on PvP server. named Pakolio, Horde troll hunter
Thanks for your time and sorry my bad english
