That's quite an unusual issue. I haven't seen it before (though i haven't really checked) not sure how widespread it could be.
They're not the same, you got phished, op used official links to fund the forum. Look at the link in the OP (click quote to show the OP as text or right click>"copy link address"). I'd recommend you switch your browser to one like Firefox which displays the hyperlink of text in the bottom right of the screen in a very small box.
