I think FB is so insistent on using real names because, through its partnership with companies like Datalogix, it allows advertisers to show FB ads based on offline / elsewhere purchases. Won't work if FB doesn't have real names. Not a fan. Have personally noticed FB ads shown to me based on my purchase of a prescription drug. Tempted to go all cash when it comes to paying for health-related and other sensitive stuff.

I'm fairly certain it's illegal to target ads based on a medical condition.

That being said, I believe you're right as to why they require real names. It's also why I use it as my go to for advertising and marketing. The added data from Datlogix etc makes it incredibly useful as a marketing tool.

It isn't illegal to target based on a medical condition. I am not making any value judgement about it, just providing factual clarification. Unless HIPAA rules were violated, there's no problem. For example, at iCouch, if they were to take diagnostic information stored on their server by their practitioner and then send out emails to the patient based on the Protected Health Information, that would be illegal. But someone visiting a depression website and then targeting depression treatment ads based on that -- that would not be illegal. Don't would depend on where the information came from that was used to do the targeting. The targeting itself wouldn't be illegal, but the use of the data to do targeting could be illegal if that data were Protected Health Information covered by HIPAA or the Hi Tech Act. Of course, I am only speaking in a US context here..

In my case, I'm 99.9% sure the info was based on my offline purchase behavior at a CVS. I had a prescription filled for a very specific condition and, a few days later, was shown a Facebook ad for a related product. Not an ad that would be shown to a general population. I had not searched about the condition anywhere online in the recent past.
