I was just playing online campaign and got kicked out..  The three other members kicked me out.   
But why? 
I  admit, I suck at games,  and am even worse online, but I was helping out, and even pointed out the witch,  which some guy still shot and got attacked. 
WTF? 
All three booting me?  I don't get it. 
I did shoot some of  my team members, but accidently, and stopped when I found out I was doing that. 
Maybe this is the reason?  
 I just thought is was F'd up. 

Yes, i was playing on the 360.  And this is my first ever Xbox.   I  always had a Playstation, and just never thought about getting an Xbox.   I couldn't turn down the MW2 edition.   
So this is what to expect with Xbox LIve?  Crazy.

Yeah, idiots do that on Left 4 Dead. Both of them. They'll do it to make room for their other buddies, or they'll blame their crappy connection on you and stuff like that. It would probably be better if they didn't let you kick people from games for stupid reasons like that.

You should definitely think about getting some people you know to play with you.  In a game like L4D where it's almost solely cooperative, it would seem like it could be ridiculous trying to get some of the douches online to work as a team.

But that's why I was so surprised.  I was helping, and if one member dies, isn't it almost impossible to get through a level with even just three?  When I was left for dead (3 times) they got over come pretty quickly.

If you really were playing like shit, I fail to see how you could be angry.
 
If you were making a few mistakes and tried explaining you were new, they probably just didn't want an inexperienced player.

L4D is a game that is easy to get kicked. It's very common in game I've participated in for the host to kick anyone making the slightest mistakes.

mean people are mean.

I got kicked out in a vs game. Some guy said tk and called a vote and I got kicked for no reason at all. I was trying to help my team too, what a bunch of assholes. This was on the PC btw.

I was playing Left 4 Dead 2 Versus the other day, and me and two other players decided to kick this other guy because he kept going far away from us and holding us back constantly. He was a guest on another player's account that was on the opposite team, and he sent a message saying "Why?". I didn't get a chance to respond to it since it was at the beginning of the campaign.
 
If they had a mic, and had explained to us that they were new or something, then there wouldn't have been a problem. But when one player who doesn't talk is constantly doing things to cause our team to lose, and thus causing us not to have as much fun, then yes, they should be kicked.
 
It sounds like you had a mic though, and that you were helpful. In this case, they might have been friends who wanted another friend to join, or for some other reason. Either way, you don't know their reason, so I wouldn't take it personally. It is easy to hop into another game, and more often than not you should have a good experience.
 
 
Edit: Don't let his one experience ruin your perception of Xbox Live. Like anywhere else, there will be a lot of assholes and people who like to ruin the experience of others, but there are also many great people too that you will have a ton of fun playing with. I have experienced several of my greatest gaming experiences ever playing online. Keep playing, make some friends on the service, and you won't have to worry about stuff like this as much.

I remember in the original left 4 dead I was playing online splitscreen with one of my mates. I was quite inebriated and was slurring insults at everybody and the funny thing was my mate ended up getting votekicked instead of me. 
 
Another time we were playing versus and he got kicked because his infected score was "too low" he was just having a shitty game, it happens and really winning isnt everything.

Yeah, I just got unlucky there, I was just playing earlier today and I swear we had the best team ever. We cleared two campaigns on advanced effortlessly.

Thanks for the replies.   I'm over it now, but it did bother me when it happened.   Never happened to me before.  Just to clarify though, I don't  think I was doing THAT badly.  Yes, I did shoot them a couple of times, but it wasn't that many times!!
But I will play better!!!

This happens all the time and if three people out of three agreed, then it was probably well founded. Get over it. "

I find it funny how a lot of people kick me for no reason. I mean i don't suck or anything in fact in scavenge im usually the one to get the most gas cans. I have noticed i have been kicked by a lot of girls it may be because I'm a girl myself maybe they feel offended, maybe they feel i have to be the queen of the castle and no girl can be better then me. I find it humorous. I just have learned to deal with it. But thing is I'm glad i have good memory on who kicks me because later eventually they join my games and i kick them for no reason :) Because i have to be the queen of my castle for god sakes lmfao

LOL

THEY'RE TROOOLLLLLLIN'.

get over it. really, if you're going to continue pubbing and you don't get over it, you're going to cry yourself to sleep LOL.

Has happened to me a few times (PC version), but only because I wasn't doing to good on the infected side. Survivors FTW!

Hey man, if you ever wanna' play L4D2 hit me up on XBL: TheSulkingDead.

Thats what you would expect on the 360 version. Happens to me all the time unless Im playing with friends. Unless you play the PC version. I don't run into that problem there.

It has happened a few times in games I've been in on the PC version too.  I think most people take L4D way too seriously (especially in VS mode) and in my opinion this makes the game less fun than having a shitty player on my team.

Welcome to Xbox LIVE. Expect that to happen at least once everyt ime you play.

" they had a friend coming, or you do really suck "

" Hey man, if you ever wanna' play L4D2 hit me up on XBL: TheSulkingDead. "

friends do that frequently, I remember I assaulted counter strike servers with my friends and we just kicked and banned everyone out, it was quite fun at expense of those who were kicked. Welcome to the internet.

Locking at request of OP.
