Professor Nissaf Ben Alaya publicly denies a video circulating on social media that uses the professor's image and an attributed voice to promote a supposed prostate cancer treatment, and attributes it to AI; statement published by Kapitalis on 28 September 2026
Kapitalis reported on 28 September 2026 that Professor Nissaf Ben Alaya had issued a categorical denial of a fraudulent video circulating on social media, which the outlet describes as a deepfake generated with AI. In the statement, which Kapitalis reproduces, the professor says the video uses the professor's image and a voice attributed to the professor to promote a medicine presented as a treatment for prostate cancer. The statement says the video appears to reuse old footage, including from the COVID-19 period, with a voice or words artificially added, a method the professor attributes to AI. The professor says no permission was given, that the professor has never advertised a health product, and asks platforms and the competent bodies to identify and remove the content. The statement warns that such videos can harm the reputation of the people shown and put the public's health at risk. The report does not say who made the video or whether it has been removed.

AI system as recorded: Unidentified AI tool reported to have been used to attach a voice or words to old footage of the professor (the professor's statement; Kapitalis calls the video a deepfake generated with AI)
What Happened
The video. In a statement reproduced by Kapitalis on 28 September 2026, Professor Nissaf Ben Alaya says a video is circulating on social media that uses the professor's image and a voice attributed to the professor to promote a medicine presented as a treatment for prostate cancer. The statement says the video appears to use old footage, including from the COVID-19 period, to which a voice or words were artificially added, and attributes this to the new possibilities of AI. Kapitalis describes the professor as the victim of a deepfake generated with AI.
The denial. The professor formally denies being behind the video or its message, says the professor has never advertised a medicine or health product, and says no permission was given to use the professor's image, voice or earlier appearances to promote a commercial product.
The warning. The statement says fabricated declarations attributed to a health professional can mislead the public, harm the reputation of the people concerned and create a real health risk when supposed treatments are promoted. It asks people not to share the video and asks platforms and the competent bodies to identify and remove such content.
Limits. The account is the professor's own statement as carried by one outlet. The video was not seen. The report does not say who made it, on which platforms it ran, how many people saw it, whether anyone bought the product or whether it has been removed.
Reported harm
A video used the professor's image and an attributed voice to promote a supposed prostate cancer treatment the professor says the professor never recommended and never authorised; the statement calls this a deceptive usurpation of a person's identity, and the professor issued a public denial (the professor's statement, reproduced by Kapitalis).
Outcome
UnknownThe professor issued a public denial and asked platforms and the competent bodies to identify and remove the content (statement reproduced by Kapitalis, 28 September 2026). No complaint, platform action or investigation is reported.
What remains unknown
- Who made the video, which tool was used and on which platforms it circulated.
- Whether the video has been removed and whether any complaint was filed.
- Whether anyone bought the promoted product because of the video.
- Where the statement was first posted.

TV presenter Bettina Tietjen warns on Facebook in September 2026 that fake videos, described by outlets as AI deepfakes, show her advertising a remedy for Alzheimer's, and says scammers are behind them
Bettina Tietjen, host of the 'NDR Talk Show', wrote in a Facebook post on Tuesday 29 September 2026 that videos were apparently circulating in which she advertised a remedy for Alzheimer's. 'Das sind Fake-Videos, dahinter stecken Betrüger', she wrote, asking people not to fall for them. The spot on news agency (via Abendzeitung München) reports that she has nothing to do with the advertised product. MOPO describes the clips as fake AI videos, and spot on news and TAG24 say they are apparently deepfakes made or altered with artificial intelligence. No report says whether anyone bought the product, and no complaint or takedown is reported.
Padre Diego Jaramillo of El Minuto de Dios says in February 2026 that videos, described by his organisation as made with AI and with a voice that is not his, falsely show him selling collagen and health products
On 23 February 2026 the Minuto de Dios organisation issued a public alert that ads circulating on social networks used the name, image and AI-manipulated videos of its president, the priest Diego Jaramillo Cuartas, with a voice that is not his, to make it appear that he recommended or sold health formulas. In a video published on the organisation's channels, Jaramillo said his image was being used as if he were a collagen seller and that this was totally false. The organisation called the ads deceptive advertising and said it was seeking their removal and reporting the facts to the authorities. No report says whether anyone bought the products.
Actor Tony Ramos's interview on Ana Maria Braga's 'Mais Você' is digitally altered and redubbed into a fake advertisement for a prostate remedy, reported as made with AI; Terra reported his team's warning in December 2023 and he recounted it on 'Roda Viva' in September 2026
Terra reported on 6 December 2023 that the team of the actor Tony Ramos, then appearing in the telenovela 'Terra e Paixão', had warned that an interview he gave to Ana Maria Braga's programme 'Mais Você' was digitally altered to promote a supposedly miraculous remedy for prostate hyperplasia. According to the team, his words were edited with advanced technology to make it seem he endorsed the product, his voice was redubbed, and the original footage was a tribute to fellow professionals. Terra describes the clips as fake videos created with artificial intelligence. On the TV programme 'Roda Viva' on 28 September 2026, Ramos said his image had been stolen from that interview, badly dubbed and made to sell a prostate medicine (Estado de Minas, 29 September 2026), and Estado de Minas describes the clip as a deepfake that circulated on social networks. No buyer losses, complaint or takedown are reported.
Montreal: Dr. François Marquis, chief of intensive care at Maisonneuve-Rosemont Hospital, says AI deepfake ads using his face have sold supplements and cancer cures on Facebook since at least August 2025, and that a scam victim who paid hundreds of dollars for pills that never arrived came to the ICU demanding a refund
Dr. François Marquis, chief of intensive care at Maisonneuve-Rosemont Hospital in Montreal, told CBC News (August 2025) and CTV News and CBC News (September 2026) that AI-generated deepfake videos using his likeness keep appearing on Facebook, selling joint supplements, pills and cancer cures and spreading anti-pharmaceutical claims; the latest offers $1 million to dissatisfied customers. He is not on social media and learns of the videos from people who call him. He recounts that a person who paid hundreds of dollars for pills advertised in one of the videos, and never received them, came into the ICU demanding his money back, which he describes as a security problem for the hospital. He has reported the deepfakes to Quebec's College of Physicians, Montreal police and the platforms, but says new videos keep appearing. The makers of the ads are not identified.
