The message that comes up it ' player X has teamhit you, press M to report if you think it was intentional'. Its not the exact quote, but thats what it says essentially.
Wrong. That's not what it says. That was what it
used to say, but chadz changed it almost immediatly to show that it was not just for
intentional teamhits, but for
all teamhits.
Here is what it says now: "wounded by *insert name*, hit [M] to report [15 seconds]"
IIRC when the report system was introduced and it had the text you referred to, many people where complaining about being reported for accidental teamhits. It was a
discussion whine topic about how someone got kicked when they only did accidental teamhits and how the reporter should be banned for griefing. It was either chadz or Cmpx who responded and basically said "you can report for any teamhits. If you teamhit someone, they are in the full right to report you. Watch your swings". The part about "if you think it was intentional" was only there for a very short time and never meant to be the
only time when you are allowed to report someone.
Also: Not to be a dick or anything, but if you did a bit more in the Ban/unban section, you might have noticed what the text actually says, considering the teamwound message is what you would be looking for in 9/10 cases.
