That's a pretty silly concern. There's 738,000 Google hits for Stefan Molyneux, this thread is never going to crack the top thousand. It won't crack the top million for "cult", rot13 or no. And even if it does, so what? Oh no, a discussion board mentions cults in passing - that's never happened before! If someone is searching specifically for this thread then they'll find it but that's probably a good thing - who is going to be looking for a reason other than a followup argument referencing it? I'm all for Google paranoia, but there are limits in all things.

Rot13 is active interference in the conversation - I'm fine with that if there's reason, like avoiding spoilers, but if there's no reason, then you're being silly and wasting my time. "Phyg" is annoying and poserish, and "Fgrsna Zbylarhk" is just obfuscating information that you're intentionally trying to pass along in an offhand comment(i.e., one that you're supposed to be able to process quickly).

And yes, I knew when I made that post above that I'd be giving him +rep far outweighing my -1, and probably giving myself just as much -rep. Oh well. If karma actually mattered, I might worry about it.
