Why don't you guys try teaming up yourself? It's not bad, and if you don't like it, just try it. Normally big teams are quite easy to destroy, because they are unorganized. When I was new to the Survival Games, I made big teams of more than 5. We normally lost like 3 people at the bloodbath, and it would be very few of us left. Now I am a part of a big team that has like 10 people on a server at a time, when atleast 2 of them start playing. We rarely lose, and most of us make it to the top 10, even with such a big team.
In the end, teams really aren't awful. Most aren't very good. Skype teams are quite good, and if you want to make one, you can make a post in the Survival Games section of the forums to advertise it.
People normally hide because they don't have any good items and are out of food, so if they try to go somewhere else, they have a high chance of dying. I once hid in the trees in the cornucopia because I didn't manage to get any items. After that I just died. The problem is, most people don't know when to do /suicide.
Teams that don't kill each other is the EXACT SAME thing as the people that team up. The point of being a team is that you don't kill each other!
Spammers are annoying, but if you want to get rid of them, you can report them here on the forums. There is a whole section for it! All you need is a screen shot. If you're waiting for someone to get banned, you can just switch servers. It will take 10 minutes max to find a new server and get in, just 10 seconds if you're lucky.
Just ignore sore losers. They aren't that awful, but yes they are annoying.
There is nothing wrong with AFK people. For tributes, read what I said for people that hide. For spectators, they get bored and start doing other things while staying on the server.
Noobs are just new to the game. Give them a couple days of playing, and they will be pros.
Read what I said about people who hide, because this is very similar. People run because they are just low on health from recently battling someone, or because they have much worse items then their attackers.
Also you should have made this poll multiple choice, because only being able to choose one option can be bad for some other people.
