Someone recommending the closure of # accounts and rotating keys, passwords, and anything else that KB has touched.

I probably have not been as vocal about it, but ever since I personally discovered (very early on in KB's existence) that following their default instructions uploaded your # to their server, I have recommended avoiding them, cancelling any keys used with them, closing any existing KB accounts. I still feel that way ... and tying up with # is unlikely to improve my opinion of them.
