> Even something as simple as prepending the site name in ROT13 to a reused password greatly reduces your exposure to the sort of background infosec threat radiation that's like 99.99% of the threat model for most people

If one goes with the infosec advice that you should calculate the entropy of passwords based on the assumption that the attacker knows the password scheme, then this password scheme provides zero entropy. So if there is zero cost for the cracker to pwn you as well as all the others that don’t have this kind of leetspeak obfuscation then you’re still pwned.
