He goes on to state "everything you see here is copyrighted". I can
understand that may apply to stuff HE contributes.. but what if its text
or intellectual property submitted by another (such as his subscribers?)...

I doesn't seem reasonable that HE could copyright anything but his own twisted ideas.  In just a quick google search, I found the following page that has some interesting info. 

http://www.fplc.edu/tfield/copynet.htm

I just skimmed through it, because I kept losing consciousness, and drooling on my shirt.  I did notice the following section:

Private lists.
"Private" lists are possible. All who sign up might expressedly agree, say, not to forward list messages. Also, list messages could be archived anonymously, if at all, or access could be limited by use of passwords.

Private lists should have few "fair use" problems; permission to use others' posts should be limited mostly by what they agreed to when joining, not by copyright law.

I think he'd be hard pressed to act on his threats, especially considering the number of charts, graphs, and info that the list has posted from books and other sources.  I say BS.
