It happens all the time man. We don't appreciate people that come here for answers enough. All you can do is your best to try and educate people or at least steer them in the right direction. Otherwise, if you worried about this kind of stuff all the time you would have the weight of the worlds exotic animals on your chest. The majority of people don't do things incorrect because they want to. They do things incorrect because they don't know any better.
