The episode thread are supposed to be free of comic talk. I would guess that anyone who dropped an outlandish spec that turned out to be true and from the comics would get a warning at least. You'll have to excuse my example for being "unconvincing" to you, but for those who have not read the comics and have picked-up that Andrea was not killed there, you should be able to see how comic readers might consider that spec wildly incorrect when it would not be.
I find the example of "broad plot points" like Aaron being suspicious pretty unconvincing as most every single person who watched, no matter their comic/spoiler background, found him rather shady or at least too good to be true.
