why is it

not everyone but alot of the players i have come across tend to be not very friendly at all .This is supposed to be a fun gaming site not "i hate all of you and i am sticking to it" attitudes.Again not everybody.Just an observance.

Well, have you ever looked through some comments on Youtube. A general rule you have to keep in mind is: people on the internet stink.

Now, this doesn't mean that everyone with an internet connection is per definition not a nice person, but in every community there are people that are there to ruin the experience for others. However, if you report these players to a moderators or admin, they can make sure that measures are taken to discourage that kind of behaviour and make this website a better place.

However, admins and moderators can't be anywhere, so I'd suggest to report them (so the admins and moderators know about them) and then just ignore them, because usually they are only looking for attention.

It's hard to report many players because their actions aren't enough to warrant any punishment; they're simply not nice people. But this is the same in real life, there are both friendly and unfriendly people. Just because D12 is online does not mean these people don't exist.
Edit: I hope you aren't referring to me

I'm with Cireon, my general experience has been that these people are just seeking attention. If you ignore them then they get louder at first, which might make them do something big enough to get their chat blocked, but after prolonged ignoring they give up and go away.
