I say leave her alone, do you honestly think anyone likes being hit on like that. Besides, it doesn't really matter if Cottontail is Miley Cyrus. Either way, Cottontail is still an abdl just like the rest of us here. And most all of us use screen names to protect our privacy- for a reason.
All I can say, is that Miley outright saying she is an ab on tv is awesome. That takes courage trying to get general society to accept we are not all sickos or pedophiles. And it will take even more to get society to realize we are perfectly sane and normal people too (well, most of us all are).
