The HSUS was found to have made unfounded allegations to the UK Sunday Times regarding allegedly illegal sales of ivory between African nations and China. Extensive investigations by the CITES Secretariat, ICPO-Interpol, the World Customs organization, and the management authorities of the countries involved, all failed to substantiate these HSUS claims in any way. The Secretary General of CITES has written to the HSUS, expressing his concern that the allegations were allowed to become public before their veracity had been properly examined by an official enforcement or investigation organization. The CITES Secretariat regarded the allegations "unfounded". (See CITES Secretariat Notification 200/060)

The IFAW produced a 23-minute videotape on Canadian sealing that was deemed unsuitable as evidence against Canadian sealers, and tossed out of court by Provincial Judge Robert Fowler, who labeled the IFAW camera man as "a sophisticated con man" and cited 77 gaps within the tape and a 10-month delay by IFAW before delivering it to Canadian authorities. Judge Fowler believed that the purported documentary was deliberately manipulated, and did not represent a truthful depiction of action by the sealers involved.

The British Advertising Standards Authority found an IFAW advertisement purporting to show cruel practices against foxes and hounds, lacking in evidence and misleading. The IFAW ad claimed a film clip shown, represented current practices by fox hunters. The clip was thirty years old.
