I already received several reports from users who have been asked to sell or trade their account or to give/share it for free. Especially accounts with low IDs seem to be very popular.

Account trading does not make sense and Unreal Software will ban involved accounts whenever we detect that an account has been given to another person

Never give your account to third parties. Each account is bound to its owner. It makes no sense to simply change the owner by giving the account to someone else.
Also a lower ID gives you absolutely no advantages.
