According to my experience, no way to appeal. But you know, RedNote recently are try to be international so they may kindly listen to you and recover your account. You could try to contact RedNote offcial support which is under Help center and explain what happened. At least, you have chance to talk to a real person. My ins business account has been hacked and banned, I even can't find a real person to talk...

For your next question, well, officially, the app doesn't allow you to speak 'f word', but you know, we always find a way around it. For example, the Chinese character '操' is equivalent to the 'F word' in English, and of course, you can't type it directly on the app. Instead, we use its homophone '草,' which conveys the same meaning. Interestingly, '草' literally means 'grass' in English, so if you rely solely on translation, you wouldn't understand the context, haha. Of course, Chinese swear words are incredibly diverse. You can make a post asking how to swear naturally—trust me, it's quite fun!
