There is a difference between strongly suspecting and knowing for sure, and accusing people of faking their own death is not something you can do lightly. So while I suspected, I've never seen any actual proof (and trust me, when we started suspecting, we looked), and this is the first I've heard of her having internet presence of any kind. It's a relief to finally know I wasn't crazy to suspect, but I honestly didn't think I could have just said "I think maybe she's not dead but I'm not sure and I can't prove it."
