Herkulesas

Hi everyone, so i've been playing l2 today with 2 clients, i was farming on my main char and on box i had opened shop for selling stuff as always. So, my box got disconnected, i tried to log in again but it said ,,Due to suspicious activity, this account has been locked". I have no idea why and whats the point to lock account with level 1 dwarf who just sells/buys stuff. I havent done anything illegal, didnt buy any adena from Adena sellers, im not using any illegal software. Contacted ncsoft support, but maybe u have any tips and answers why this happened to me? pretty ironic that ive been reporting bots and got blocked myself
