Not exactly respectable to tell someone to unbindall, but if you enabled console access, you've assumed the risks of using it. If you believe someone saying something suspicious like "unbindall" and do it yourself, IMO you kinda deserve it.
Basically, similar to what Katze says: It's on you for being foolish enough to unbindall, but it's still a bit of a dick move to suggest it. I wouldn't call it a punishable offense though.
