Cause they don't agree with your opinion and they're not mature enough to accept the fact that people may disagree with them, so they block you.
It's funny how @Esplorare says she doesn't care, but she blocked me months ago because I disagreed with her hahah Anyways... xD I've been blocked by many people, and it's always due to a disagreement. I haven't blocked anyone though.
I can only think of one person who has blocked me, and it's because I blocked him first. He was becoming too creepy and wouldn't leave me alone. In that case, I was blocked just to reciprocate the action.
However, it seems many people block others because they disagree with something someone has posted, whether it's a valid reason or not. Users get blocked for having different political and religious views often. Anything dealing with differing opinions is a huge factor really.
Who knows, I have had people do that. I just block them back and then just think "Meh well that is unfair and then think who cares". I have also had some girls on here post mean things on my questions and then block me before I can even reply.
I don't know. I don't care. I enjoy coming here to help people with problems that are heavy on their minds. The way I see it: when someone blocks me, they are blocking themselves from my ability to patiently work through issues with them and help them come to positive solutions.
I have no idea, i've had two block me from when I started the site pretty much, never said a single word to either of them. I think they like being the only ones who use the site or only want to see people's opinions if they agree with them, fear of others who aren't like you must be a horrible way to go through life lol
I don't know if people block me./... and i dont give not even one percent.. i am not here to make friends with no one... so if someone blocks me :D yay good for you.. since i dont even want to talk to you... so you are doing me a favor :p
