I'm going to go out on a limb and say that I honestly don't think Ed knew about the deleted posts. Or he might've known they existed but not what they contained. Just from a logical standpoint, there is no positive outcome that could come out of posting this almost 3 months later if he had. The vast majority of the vitriol directed at the Lowers for the blog itself and then the deleting of the posts was when Ed was in the house and then when he was zipping across the country for Ch 9. I fully buy that he didn't see them during that time. And then all that hate about the blog disappeared on their SM accounts so what would he gain from dredging it up again? I just can't think of one decent reason he'd do it if he'd read them.
I hear ya, but they know the positive and negative things people say about them. Hell, Nick had that whole exchange on Instagram with someone going after Ed. People have gone after Nick for his comments, very passionately. I don't believe for a second Nick has never discussed the vitriol he's received because of the blog. And, I can't accept Ed reads all the negative stuff except those related to his family's blog.
