I am with you on that one. Chat rooms are filled with so much bullshit (largely due to script writers of the more narcissistic kind just wanting to advertise their script) these days and the last thing I need to know is what song others are listening to - hence the need for a basic filter which I made for my script. It is just an ON TEXT, ON CTCP and ON ACTION effort that listens for tokens like .MP3, etc. It's possible for such scripts to filter out parts of a legitimate conversation but I have never encountered this.
Admittedly, and due to a huge barrage of pressure, I distribute a script with both the MP3 banner (turned off by default) and the above-mentioned filter, but I have made an attempt to make both as unintrusive as possible. On the network I use there are rooms that simply don't even allow them when accompanied by script advertising, something that is beneficial in my view.
