Multiple accounts / Battling Gyms

[widdin]

1.
Account A = 100% Legit leveled up with the phone, no spoofing.
Account B = 0% Legit leveled up, used a Bot.

If i login on account B on the same phone as account A, is there a chance i can get banned on account A because account B cheated?

2.
I've heard you get banned pretty fast for using Bluestacks / Nox, is there any other software i can use to battle gyms?

3.
Is there a high risk of being banned if you use Joystick on a phone?

If you want your main account to be safe dont bot or login through modified apps or emulators at all.
Everything else isnt safe, Im not saying they are gonna ban you but you should take care if you value your account.
You should be fine playing normally with your phone.
