People manage to find the answers that they hope are correct, and to disregard the advice that doesn't quite fit with their view of what should be true or what they wish is true.
I especially enjoy the threads in which the poster asks if he/she can do a particular something. A dozen or more experienced posters will say "No, you can't, and here's why..."
The original poster then asserts that they have read the exact opposite thing "somewhere", and that they now intend to do it to see what happens.
In a world where literally anybody can post literally anything...and where a million gullible saps will read even the most outlandish and ridiculous crap and assume that it must be true, 'cuz it's on the internet...no, sorry, I think that all this misinformation and disinformation is, on the whole, more negative than positive.
