The problem with that is that somebody will have to keep count.
Are you going to volunteer?

I agree, we have enough problems with "How many rounds since the last freeday? *everyone else says two or three* OKAY! Let's have a freeday!"
As stated in the code of conduct section on the forums, us e's/pubs don't realize how much the admins do behind the scenes. Popping out an all chat warning is useful, yeah, but I noticed a lot of admins prefer to send a private chat. I only know this cuz my girlfriend (Black Angel) is an eG, and I love to watch her play, so I can get an idea of how the admins work (you bunch of silly people).
Besides, if it's an honest mistake, the person will often admit it. Some do suicide, but others don't simply so they don't hinder their teamates (esp. when a bunch of Ts are rebelling, and he/she suicides to make only 2 CTs left). But if their freekilling gets excessive, I know for a fact the admins will revoke the CT in offense eventually (if no warning has been given out).
And finally, a person coming in just to freekill everyone and disconnect (called griefing) are always annoying to see, but remember there's a ban request section, and you can easily prevent them from playing on our servers (with legit proof of course). :3
Just remember, admins are always there to help, so if you feel you're being FK'd too much, report it to them (not spam the crud out of admin chat, but report it calmly and with a good attitude). They'll get it handled.
Hope this helps mate! Have a great day!
