My phone number has been banned on WhatsApp for bulk messaging from WhatsApp Web using a macro recorder and I immediatly ran to the store and bought a new SIM card. I created this new account but it was banned instantly (Didn't bulk message or anything, just sent some messages to some of my contacts to inform them of my new number) I tried this like 3 more times and they all kept getting banned so I went to starbucks to create another account (Because I guessed my ip was banned?) and I was able to have that account for like 30 minutes until I connected it to WhatsApp Web, and it was banned again. I tried it yet AGAIN and my current phone number hasn't been banned for like 3 days. Before creating that account I resetted my Advertising Identifier (I'm on an iPhone) and disabled iCloud drive backup for whatsapp. I haven't connected my phone to whatsapp web yet because I'm afraid It will get banned too. Do you have ANY idea of how WhatsApp identifies unique devices? Or any iOS app for that matter? Keep in mind Apple is very strict about their privacy policies and usually don't allow developers to uniquely identify devices.
