Abuse at the table

So I was playing in one of the William Hill Headhunter tournaments last night, quietly minding my own business, when a hand came up against the tournament chip leader at the time.

I had doubled up with trip kings a few hands earlier, then got moved tables. Blinds were 75/150, and I had a stack of around $7000. I got dealt A8o in mid position. All folded to me, I made my standard 3x raise of $450. All folded to chip leader (with about $8500) who simply called in the small blind.
Flop was x67. He checked. Now I would usually put out a continuation bet here, but I had this feeling that I would be check-raised. My thinking was that you don't get to 8500 in chips early without being aggressive. Aggro players don't check. I therefore checked behind for the free card.
Turn was a 9 giving me an open-ended straight draw. SB put in a bet of 600 which was about half the pot. I was getting about 3:1 on my money, and if I hit, I could get paid by the aggro player, so I called.
River was a 5, giving me the straight. He bet, and I pushed. He called showing QQ.

I had doubled to a big chip lead with $14,000.

The guy then started berating me big time calling me all sorts of names under the sun. I kept quiet. The funny thing is that he misplayed his hand, and started accusing me of being a calling station. He then turned to a verbal tirade in German. My German certainly isn't good enough to work out what he was saying, but it was fairly obvious it was not pleasant. Anyway, I decided to copy the chat just in case it was nasty. The guy moved tables a few hands later.

In the meantime, I posted the chat on a couple of forums to see if I could get a translation from native German speakers.

We both ended up going deep in the tournament and the guy got moved to my table a further 2 times. On each occasion he would continue to call me names. This I could put up with as I could ignore it, but the worse thing was that he would comment to everyone else when I was in a hand. For example, I made a pre-flop raise first-in from cut off (with JJ), and he wrote "he's bluffing".

After the tournament, I checked the forums and found indeed that what he said wasn't pleasant (I won't repeat it). Everyone said I should report him, so I did.

We all get comments from time to time, but this went too far. I did not suck out on him, he misplayed the hand (I didn't tell him that). But to continue over an hour later, and make comments when I'm in a hand is simply inexcusable. I admit, it did put me off my game a bit, and I didn't play that many hands whilst he was around (although I was card dead for most of the time anyway).

I hope William Hill take some action, even if it's a temporary chat ban for him.
