Many people get banned, ask what happened (most are just acting innocent), and when someone quotes what they did, they say "Ok" and leave. It's usually pretty much just a waste of time.
Some might be farmers trying to figure out how to avoid this going forward. Some might be genuinely clueless because they bought the account. Some might be hoping to leverage some fallacies ("only did it once") in their appeal. Waste of time is correct in most cases though.
Because gambling just need some knowledge and well management of risk. So, if we have capability to manage our risk. Then making big profit from gambling is so easy.
