I contacted support and after 4 hours sent this:
Dear user,
You should know that administration has all necessary information and equipment to detect all the stuff related to your situation.
You account has been banned due to project rules violation "User’s obligations" 2.2:
q) Trade game items/accounts between different servers of l2e-global.com or other resources and also using non-game contacts for trading game items
If you want to help us in our investigation then provide all information related to the violation "User’s obligations"
If you provide false information you will violat Point 2.6:
"User is obliged not to provide false data to other user or administration while submitting application to support department or cooperation in investigation like informant etc."
Such actions decrease your chance to continue playing.
