Why are some people so ignorant on here that when you ask a serious question all they do is attack and say?

you are a troll or lying because you mistakenly used the improper grammar say "He could of" instead of "He could have".....Or they say im lying for attention??? REALLY??? I mean, this is sad.. yahoo answers has turned to cyber bullying....isn't there some rule against this? Do people think that they are really so high and mighty? They all remind me of my ignorant child like husband.
