Well technically no, all cheats are are not allowed, however I have never had or heard of any any problems playing online on solo. As this cheat isn't like other cheats in that it doesn't make you invulnerable or infinite ammo etc it won't attract attention. It is when people use cheats to extreme and end up at level 9999 on the leader board that they will be banned.
