it is not safe atm to play against players at all. If your going to bot do VS AI
EDIT:
to clarify I meant that you should not disrupt the player experience because the bot is not up to par (it's still in beta) Still in terms of if you get caught/banned I would not recommend it, as always no one can say for sure. never bot what you are not willing to lose.
I would NOT use this in any other mode other than the AI one currently. it's way too easy to pick up that it's a bot. I already seen multiple people in QM and even HL getting reported...
