Account terminated - whatelse i can do to get the access back

Today I got an emajl saying my access is terminated because of violation of policy. I have a public app but my mistake i didnt use the moderation api so likely some user used some bad words or sentences which violated the opena policy. It was a mistake to use got api wothout moderation api. I didnt know there was a moderation api tbh. But it was a mistake. I use chatgpt for my normal day to day general work as well now as my access is restricted i cant use. If a warning would have been given then i would have got the idea that there is something wrong. I appealed the ban but dont know
What else i can do to prove that this mistake ll not happen again and get my access back.
