Similar stories have flooded anti-vaccine forums and messaging apps in recent weeks as some customers and donors raise doubts about AFLD. The group describes itself as a “non-partisan” group of medical professionals. But it originated as a right-wing political organization, and since its founding has consistently spread medical misinformation. Its name implies the group consists of physicians on the frontlines of the pandemic, but it’s not clear how many of its members have spent any time treating patients with COVID-19.

Its followers aren’t the only ones with questions about AFLD. It’s hard to pin down how many people the group employs, how much money it’s taking in, or how that money has been spent, in part because the non-profit has failed to file required disclosures. After it failed to submit its annual report in Arizona, where the group is registered under the name “Free Speech Foundation,” the state recently downgraded the organization’s charitable status to “pending inactive.”

Over the past three months, a TIME investigation found, hundreds of AFLD customers and donors have accused the group of touting a service promising prescriptions for ivermectin, which medical authorities say should not be taken to treat or prevent COVID-19, and failing to deliver after a fee had been paid. Some customers described being charged for consultations that did not happen. Others said they were connected to digital pharmacies that quoted excessive prices of up to $700 for the cheap medication. In more than 3,000 messages reviewed by TIME, dozens of people described their or their family members’ COVID-19 symptoms worsening while they waited for an unproven “wonder drug” that didn’t arrive.
