This module gives you the +D channel mode that disables CTCP ACTION's (/me's) on channels, the +m user mode that does the same for users, and the +M user mode to deny DCC's from sending to someone having the mode. The purpose of all these modes is to extend the builtin features of UnrealIRCd to let you be able to completely disable CTCP messages on users and channels.

Personally I don't see much usefulness in denying /me's (CTCP ACTION), but the 'deny dcc mode' could be useful to some networks, like if you set it by default via set::modes-on-connect and then allow users to unset the mode if they want to.
