A website was erected by Henderson in 2000, in consistency of his first book and also named Crimes of Persuasion. COP extensively describes the methods used by criminal perpetrators, like deception and deceptive persuasion. The site states as its mission: "To inform the public, along with law enforcement personnel, justice officials and victim support groups on the workings and scope of telemarketing and investment fraud so that efforts can effectively be taken to minimize the impact on its victims and ensure that adequate penalties are in place to deter the perpetrators."

In 2002 a Forex operation sued Henderson, forcing a temporary closure of his site pending a multi-million dollar lawsuit against him for defamation. There are no references to the outcome on COP or anywhere else.

June 2004 Henderson and others were served with a lawsuit by Fashion Rock, LLC (aka Talent Rock), a Florida company then owned by con man Lou Pearlman, accusing them of "violation of the federal and Florida versions of the Racketeering Influenced Corrupt Organizations Act, tortious interference with business relationships, defamation, false light invasion of privacy, misappropriation of trade secrets and civil conspiracy". The suit was dismissed.

Also in June 2004 about a dozen identical sites were erected by Fashion Rock CEO Mark Tolner "to attack critics" (a.o. Les Henderson and Ripoff Report), Shortly thereafter the "Bureau of Ethical Internet Commerce" was put up by Ayman Ahmed El-Difrawi (an ex-con for fraud and Pearlman's leading consultant in his talent scouting businesses) for apparently the same reason. Several anonymous writings, containing unsourced offensive allegations about Henderson, have appeared on message boards, blogs, press releases and mock sites that can easily be found on the Internet. Henderson in return successfully filed a libel suit against Pearlman, Mark Tolner, Ayman El-Difrawi, and several other corporations and individuals. Difrawi and three other defendants were ordered to pay Henderson $10.000 each "for their part in the creation, publication or republication of the libellous statements",

In November 2007, St. Petersburg Times personal finance editor Helen Huntly reported that El-Difrawi had founded a business and web site also called Crimes of Persuasion imitating Henderson's, using his real name.

On November 21, 2007, Ayman A. Difrawi and Internet Solutions Corporation filed a lawsuit against Henderson and others, accusing them of defamation, trade libel, injurious falsehood, false light invasion of privacy, civil conspiracy, and RICO violations.
