“YouTube has banned a group called the Rational Response Squad after it complained its videos were being taken down due to spurious DMCA requests from creationists.
“The takedown followed copyright requests sent by Creation Science Evangelism Ministries, an organization founded by currently-imprisoned tax evader Kent Hovind. The Squad says the clips comprise material that is either public domain, covered by fair use, or entirely self-produced.
“This again highlights a central problem with the DMCA, namely that it forces takedowns without any kind of review, and puts the burden on proof on the ‘defendant’ to show that its material is non-infringing. But to ban people for protesting when the process has been used illegitimately is something entirely different. The creationist ministry’s own website said that ‘none of the materials … are copyrighted, so feel free to copy these and distribute them freely.'”
