You’ll often see a copyright “notice” – the familiar © or the word
“copyright” with a date and name of the copyright owner - posted on
works of authorship. This copyright notice is no longer required for
copyright protection, but it may be a good idea to use it.

Copyright is a legal form of protection granted by the U.S. Constitution
for original works of authorship. Things such as books, plays, music,
photographs and even websites are protected by copyright law.

Most sites on the web are at least faintly familiar with the implementation of legal regulations related to their sites. Most, however, have never heard of the California Catch-22.

Most sites tend to view complying with legal regulations as a somewhat amorphous subject. You know you are supposed to do something, but are not particularly sure why or what to do. This leads to the rather humorous situation where many sites have terms and conditions that are completely inapplicable the what they are doing and also look startlingly similar to terms and conditions found on other sites. One might even imagine a bit of “cut and paste” was going on, but who am I to say!
