Interesting.
So based on these (multiple) reports, it seems pretty clear that They Are Watching, and contrary to several of the posts earlier in this thread that seemed to take the attitude of "nah, it's way too early for anyone to get into trouble with Bluebird, nothing to worry about...." (I paraphrase), apparently it does not require extreme "abuse" to get their attention. Something as seemingly benign as a married couple both linking their Bluebird accounts to the same joint bank account may result in an account lock. OK, not exactly a Paypal-esque smackdown, but still something I'm sure we would all prefer to avoid.
Thanks for the info and linky.
