Why my account was banned?

[BIA_MuxauJL]

Admins, I played on Lost_Normal_EU, I was banned without reason, after that I saw that my account was banned too, after first kick I connect to that server again, to see why I was kicked, but admin don't explain reason(I asked "WHY?" 3 times), ok, after I continue play, and over 5 minutes I was banned in site and in all servers. Please Unban me  :'(
P.S Sorry very mutch for my bad English.
