Me cheat?

As I have mentioned before, one of my favourite games is Command and Conquer Renegade.  I first started playing this game a little after it was released, back in 2002.  Online only.
For the last couple or so years kept playing by 90% to a specific server, nice guys the owners, nice guys the players.  All was great.  For a brief time I was even promoted to a moderator there.  
At one point, like a month or a bit more ago, one of the owners of the server, let's call him W1, asked me to take a test, cause he believed I was cheating.  I hardly ever played against this guy.  Anyway, I said sure, he tested me, he found me, naturaly, innocent. Since I have never cheated in a multiplayer game in my life.  After a couple of weeks, for some reason I don't know, less and less people were playing there.  In fact 99% of the time I wanted to play the game, the server was either empty or just with 2-3 people in.  So I spent my time playing the game on other servers more time than usual.  
  Earlier tonight, the same guy, was trying to get into our base.  I saw him going in the tunnels near our base, I followed him, I entered the tunnels and went downhill towards the Nod Power Plant entrance.  Hearing the Obelisk firing I knew I was going the right way.  Got out of the tunnels and trying to decide if I should go towards the power plant or the Hon, then saw an explosion from the back door of the Hon.  I run to the front door of it, entered and saw the guy, as a the Hotwire character (I was Ravenshaw) going up the internal ramp, and trying to get out of the window.  He jumped and I shot him, he had lots of damage and I hit him with my gun, he died.  He started saying that I cheat, that he knows that I cheat.  That he knew about it for ages and other bullshit.  Bullshit not because he didn't believe it, but because it has no base to reality.
He kept talking about this, I asked for support from another owner of the server that he knows me a bit better, and he refused to take part in this.
I asked W1 if he wanted me to leave and not play there again, he said that this is exactly what he wanted and that if I would talk to him again he would ban me from playing there again...
  I left, went to the forum, posted a goodbye message, which he locked immediately.  Perhaps he didn't want to hear from people that what he did was very stupid, irrational etc etc.  Of course none would say these words since they would get banned, but you get my point.
  What a noob, nothing else.
