It's literally very different, and I don't think you understand how Twitter works.It's literally no different than if you started posting NSFW images in this thread. Those posts would be deleted and you'd be banned. By having a forums account here I haven't chosen to view NSFW images just because you decided to post them. [H]ard|OCP is potentially protecting my job in that scenario.
Do you have any idea what I have posted on my Twitter feed? Of course not, because you never subscribed to my channel.
You don't opt-in to hear what I have to say in a public forum, you do opt-in for private subscription channels like Twitter.
