I received a three-day ban even though I hadn't used anything or changed anything on my computer or emulator in a long time. After three days, the ban ended, and on the fourth day, I logged in and played. On the fifth day, I was banned for seven days. I don't know why I was banned. I appealed on the first day of the ban, but they didn't help me get the ban lifted or even tell me what program caused it.
They ban your account without telling you why. My initial goal in contacting them was to find out why; I had no doubt they were wrong. They're difficult to reach and offer no solutions... I don't know what's going on with PUBG.
