Psychologists have known for a long time that when people are wearing masks, they act wilder, more uninhibited. They will do and say things that they wouldn't do without the mask, even if the mask is not preventing people around them from knowing who they are. There is something about people not being able to see your face that unleashes human beings.
Now we have the internet, and it has the same effect as a mask. People online seem to feel more free to unleash some inner prankster or bully or just generally outrageous jerk that they apparently carry around within their pysche. I don't know whether unleashing it here makes them more or less likely to act that way in real life. I do know that if you want to ask for reassurance, an open online forum like this (where any stranger may say anything to you) is not a good place to get it. Someone might eventually do what you needed and take a look at your answers and guide you. But before you find that person, you will find more of the wild bullies than is good for you. I don't know if you have read Gullivers Travels to get this reference, but "Yahoo Answers" is very aptly named.
