Not only that: There is no quality control over it.
Friday, I watched an ad for something called "The American Parasite". It was basically making some accusations and saying over 250 million Americans have this "parasite" and it was being covered up by the government and medical fields.All being done in a ASAP Science kind of way in order to somehow get people to trust them.
Well, knowing what bullshit smells and looks like, I did a quick fact check. Turns out this "parasite" is nothing more than a yeast (Candida to be exact) that feeds on sugar. Not only that: the ad makes a whole lot of bogus and Correlation = Causality shit. All they wanted is for people to go to their complete moonbat site, watch a TL;DW video that makes even more bullshit moonbat claims, and for people to buy this probiotic crap.
The moral of this story is that it won't be long before even more moonbats with pseudoscience take advantage of this and advertise a plethora of "You can't skip these" bullshit ads selling shit and sugar.
