can confirm, ive indeed suddenly got a ban on my "test" account" just now.
I've been playing with my main since the 16mb in game update since last night (over 30 matches) and not had any problems, as soon as i noticed you guys posting about bans here i logged out of the main and logged in with the "test" account, test account just got banned.
from my previous experience with this hack (pre sanhok), once you receive your first ban, your device will be "tagged' and subsequently any account you logon with that same device will receive a ban.
