I find the comments people make hilarious. I have seen the one mentioned at the beginning of this thread often. If it happens to me I will either ignore it, or respond with "...I am only here to make you rich..." or some such variant. But like Kraemer commented some people can have their play effected by chat, and that has been me in the past. IT took me awhile to get my head out of my ass and recognize it for what it is.
If you can use it as a tool great! otherwise ignore it, just my opinion.
