did you know that you can avoid losing rate if you have another account? if u accepted a code with your original account, you just have to accept it again in your fake account with exactly the same code and system will skip your code and make round unrated for you. i think this skipping system won't stop cheating because you can copy a code and just change one word of it and it will not skip. it seems that it just make cheating easier.
UPD:pls read comments then dislike. thanks.
