But the thing is, that cuts both ways. Here’s something from, of all places, this very board, making pretty much the exact point in question:
And the thing was: I didn’t remember saying any of that! But it wasn’t that my opinion had changed, and that I genuinely had no recollection of having held the old one; it was that the other poster simply hadn’t been remembering things right, which he noted after I brought it to his attention: “I strongly apologize! :o :o Mea culpa. Yes, I confused you with Starving Artist.”
But if I’d been banned by then, and no longer able to offer a timely suggestion, he presumably would’ve gone on incorrectly figuring that, yep, thought one thing, changed his tune; says he doesn’t remember, maybe he doesn’t; oldest story in the book.
