Use spamfilter
UnrealIRCd has a very effective, but also slightly complex, tool called Spamfilter. It allows you for example to automatically GLINE anyone saying "Hi plz download: www.virus.com/this.exe" in a channel. It can react on private messages, channel messages, dcc's and more. It can use simple matching but also regular expressions. See the Spamfilter article for full information.
