I don't understand why you're being downvoted here. Sites like you describe will undoubtedly pop up around this dataset.
I think dumping the member information with email addresses, profile information could happen. Just verifying emails is already happening.
But the CC info with last four digits, addresses, names, etc. might be hard to keep visible for any length of time.
The Adult Friend hack wasn't as high profile as this one, but has largely been benign.
