I am not sure what the problem was 2 months ago, but last I checked a scammer is someone who goes steals something from someone. Did he steal anything from you?
Then I suggest you check again - as this is simply not the case. Some well respected forum members (gmaxwell, saltyspitoon) explain perfectly how the trust system works here:

You may need to learn how to read. I said a scammer. A scammer is someone who "scams" someone. If I go and and steal all your money I am not a scammer I am a thief. The trust system is a list of people who say that they do or do not trust you. They can trust you for what ever reason they like. Anything from doing a physical trade with you or simply because they like your name.
BitAffNet has never scammed anyone as far as I am aware. If you have a real problem with the pool maybe you should explain what the problem is in clear words with out cursing and you might get a response.
