Hmmm....we talked about this in the chat, i do think you may have over reacted a bit. Even if something was said that you took offense to.. the person still apologized.
You need to let things go, you came in and out of the chat a few times after that and didn't really hear soul out.

The chat is logged and reviewed from time to time so if there is a problem with a user, it'll be noticed.

Your concern is noted though..

Bob.
