dlFilter is a text filtering script for mIRC. It is created with both chat and file sharing channels in mind. dlFilter removes ads, requests, annoying KeepTrack, mp3 play & away messages and much more. Also, dlFilter can send notices from fileservers to separate window and group @find results, allowing them to be easily viewed.
On the other hand, it is a handy feature to see if server is voiced - and possibly detect dodgy servers. I am not sure how that feature is used, though
Suggest that they are removed from the Ads window.
