Anything specifically on MSPA.com has been found through the years and "exploited" to its limit. Like people mentioned, the hidden index breaks at some point, so there's a reasok people ended up having to build alternatives from scratch. There's even a secret page where you can run a Linux directory exploit... to do nothing. There really isn't anything on the server the fans hadn't already gotten to.

Very interesting to hear about the early Psycholonials site, though, I didn't know that.
