I'm no fan of Facebook, but honestly, this doesn't seem like a big deal. Actually, online ad networks like FB or Google are way more transparent than the alternatives. Sure, when you say you want to target X it's not going to be 100% X, the data is noisy. Ultimately, the data speaks for itself. You can see impressions, clicks, and conversions, and it's almost instant. If you don't like the results, you stop/change your campaign.
