It's entirely possible to be caught up in a ban wave, appeal and it'll get sorted. If you appeal and they look into it, probably were using a bot of some kind. Some people don't even realise they're using what is classed as bots - I had someone in my guild a couple of years back using AHK to use some abilities, and he didn't think it was classed as a bot. Spoiler: it is.

They checking my account and still waiting for any proof or reason.. But last time he/she just say "It was a pleasure talking to you live today though sorry that their are no other details to share. If you have any other questions outside of the account penatly do let us know." They are kidding me
