It would be great if the trust rating of the person posting was displayed next to their thread post. So i dont have to click on the thread to see that it was posted by a scammer. That would be donation worthy to me  

Huh. That could be useful. Maybe a checkbox option in profile menu to turn it grey like an ignored person's, or grey out the OPs name in thread-browsing, or red it out. Something simple to let people know there's something up before they even click without being too in-your-face.
An option to automatically ignore people with a negative overall rating might be interesting, too. Maybe the server would maintain the list, a user can click "add negatively-repped members," and have the list populate from server data. This would also achieve the effect of graying out neg-repped OPs.
