Very interesting post. I for one agree I do not want child porn etc in IRC chat rooms BUT and this is a big BUT, chat rooms are not governed by the United States or their laws nor should the client mIRC. It is used internationally and I am an example of an intenational user who is NOT governed by United States law.
By making an irc client illegal (so to speak), is like making us not use IE or firefox or whatever browser we choose to explore the net. Can't be done, shouldn't be done
Such chat rooms can be avoided... don't go in them. However if someone does see such acitivity that's why there is the logging system in mIRC.
Just my 2 cents worth...
