You're thinking of something else (and "purged from the internet" isn't exactly an accurate account of that, either).

Genuinely curious… What is the other thing?

I do recall there was some recantation or otherwise distancing from CEV not long after he posted it, but frankly it was long ago enough that my memories might be getting mixed

What was the other one?
