If you'd like the "Orange Hellsite" to stop showing up in your browser history, enable "noprocrast" in your Orange Hellsite profile, then set maxvisit to 1 and minaway to 700 or something similarly large.
Nah. That only works if you are logged in. It's trivial to delete and account and make a new one. There's nothing particularly special about one's account (and, in fact, I regularly delete mine and create a new one so I don't get too attached to the 'number going up' on the karma.)
