IP Ban Options

[Eva]

Hello!
First I would like to ask what an IP ban is and how long it lasts and second I would like to discuss some other issues.
My steam profile is http://steamcommunity.com/profiles/76561198202328987/ and I know I have been far from an exemplary player!
The ban was probably a couple of days ago, I imagine because of a teamkill although can't be sure.
It would sure be great if we could discuss this maturely, although at times I'm considering quitting the game all together due to the issues I mentioned earlier. (I can elaborate if you want but I don't know if this is the right place for that.)
Looking forward to any reply and thanks for taking the time to read this.

I'm sure you have heard about them before but for example: people who teamkill/teamdamage on purpose don't get vote kicked many times but instead people with, what seems to be one accidental kill, get voted off the server with 60+%.
Another thing is speaking in different languages...I have witnessed a lot of people doing that and for a long period of time, yet after browsing the forums for only a little while I saw that someone was kicked for it.
Also, in the case that a votekick for a troller/cheater/teamkiller fails and there is no admin to adress the issue, what is the suggested course of action?
And lastly, (and tottaly off the point, so I apologize for that), when I tried to register I never got the validation email, so I had to use a different email address to post this message. Just thought I'd throw that out there as well.
Thank you for your reply.
