Facebook collects a LOT of data on their users. It's really the product that they profit off of. Some folks find that distasteful, some don't care. But it is worth all of us being aware of.Not sure I understand all the cloak and dagger requirements for Facebook.
If something is free on the internet, then YOU are probably the product being sold. It's part of the reason that we don't run creepy ad networks here on PNWFF. Sure, we could make some money doing it, but we hate that crap. If we're going to have an ad, we'd like it to be sponsorship from the fishing industry. Not some FB subsidiary tracking you across the internet so it can show you the same ads in 15 websites.
