OK, for one thing, why on earth was this dug up 3 months after the initial complaint and ruling with no further evidence, complaints or, well reason?!
Blitz, expect a PM coming your way.
On the topic of the ruling - because we do not go into private PMs in an attempt to respect your privacy, we cannot verify the existence or content of the accusation to 100% certainty and it essentially becomes "he said, we said". Now, if you would like to petition us to begin digging through your inboxes, violating your privacy and finding all sorts of dirt on you, you are welcome to try it - but this is not the place for it.
Now, that does not mean that roadwarrior is innocent, nor does it mean he is guilty. We have noted it so that in the future if we get similar complaints - if this becomes a trend which we can identify - then we can take certain action against a user.
To all those who say "but 3 people said he did it!" well I promise you I can find 3 people to condemn you as well. Yes, it is very damning and looks bad, but you do not know the details and so are making an emotional rather than fact based ruling.
Roadwarrior, I suggest you apologize for whatever crimes you may have tried to commit and move on with your life
Everyone else, it looks HIGHLY suspicious that so many people so uninvolved in this particular case are being so quick to condemn a player - it almost looks like to have an ulterior motive

Leave accusations to those who have been wronged, those who do the wronging and the mods who's job it is to keep the peace.
The ruling will stand, roadwarrior is suspected of trying (and failing) to form an alliance via PM. Because we do not know a) what the exact contents of the PM was to 100% certainty, and b) what would have happened if the "form of collusion" had been agreed to (it may have ended up a publicly announced alliance) then technically no rule has been violated yet but we will continue to watch for further accusations which may hold merit.
Add him to your ignore list if you choose, but be done with this pointless argument.
