Back when I first started on DA, I posted Parodies of Bill Keane's daily comic strip "The Family Circus," which I entitled "The Family Disaster." Most of the people who saw them loved them, but there were some who either found the offensive, or in violation of Copyright, and they were removed. But Now I am bringing them back, because if you read this :

§ 107. Limitations on exclusive rights: Fair use
Release date: 2005-08-01

Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include—
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.

And here is the source of this information: [link]

You should see that I am not in violation, because I am giving credit to Bill Keane for his original comics, and that I am not having people pay to read these comics. So if you are one of the people who enjoyed "The Family Disaster," its coming back, unless someone gets angry again and tries to have them removed.
