I don't know exactly who told him this, but hilariousandco has a tendency to say things exactly like that in some ban appeal threads--which I disagree strenuously with and wish he would stop doing.  And I've seen other assorted noobs offering the same advice in other ban appeal threads, too.

It is absolutely against the rules to create a new account once you've been permabanned, and if mods (or anyone else) disagree with that they should convince Theymos to change the rule.  

Most of us have our eyes open and know what the rules are and what the consequences are for breaking them.  Even if someone gave you the advice to use another account after you'd been permabanned, it's still not allowed to do so.
