Your account does not have any messaging bans on record. The message saying that your account lacks permissions is unfortunately something that's been happening for a while now, but all you need to do is close the app and open it again, and that message should go away. Also, if you're receiving messages that violate the Code of Conduct, please report these messages so we can take a look. Keep in mind that we cannot see the context of private messages, only the specific message that gets reported to us.
