Rule #9 copy and pasted from the honor code says:
Honor Code violations consist of discrimination, racism, sexism, harassment,
illegal drugs, cheating, poaching, squad de-ranking, or any other overly aggressive behavior toward fellow online gamers. Cheating is defined as any manipulation of online play; this includes, but not limited to modding, bridging, stand-bying, forcing host, action replay, glitching / super jumping in match making / ranked games to gain an unfair advantage, playing online custom / ranked games with Modders, and circle boosting. Every situation is different and will be handled appropriately on a case by case basis.
Just check out the honor code next time if your not sure what is and what is not allowed. Here is a link:
