The thing about the internet is that you can read anything you have access to and you’re free to post in any social media platform to which you are granted access. If this were an exclusive community for accountants only and no one else were allowed to read or post, then it should be stated as such and others should be prevented from doing so. But, it isn’t. So that poster has just as much right to ask his question as anyone else. Just, dont be a jerk. It’s easy, really.
