Honestly, not surprised at this, but it is a devastating betrayal of trust for patients who participate in closed groups.
"In January, a complaint was filed with the Federal Trade Commission alleging the content of private Facebook health groups had been shared with third parties. Some members of these health support groups claimed they had been targeted by advertisers who had offered products and services related to health conditions that had only ever been discussed in closed, private Facebook health groups."
I will be looking into the new "Health Support Group" designation for the group I run for the GDATF, but it's going to be hard to put the trust toothpaste back in the bottle.
