just found a new glitch to put your clan tag to "COD" all you need to do is type it in like this: C(OD and it will automatically erase the "(" so you have a illegal clan tag! . also on a side note, the "3arc" does not work because you need 5 letters for that.
theres only 1 other banned 3 letter word (that i can think of) clan tag and thats C0D (with a zero) so it also works with that. guys can you also please leave a comment if i helped you?
