(I'm saying this because once upon a time I had cloned discord on my phone by installing the same apk with a letter changed (com.discore) and it thought I was using a 3rd party app or something. They asked for a number, gave me access to my account for about 5mins (good thing I thought of backing up my account and my friend IDs) and banned me. They didn't mention why, just some default message about spam. I did it again since I didn't know what I did wrong, another number down the drain. I haven't checked if they are still blacklisted.)
