DALnet has clearly said that the change in AUP is intended towards "Using a channel for the primary purpose of facilitating the transfer of files" "is not about the occasional transfer of a file between people who otherwise are using DALnet to chat. This is about setting up channels as a means to facilitate the transfer of files." and that they "respect the right of our users to transfer files between themselves on a limited basis"

They have NOT said they are blocking all files between users. As for your example of scripting channels, if the purpose of the channel is to help ppl with scripting i dont see how they would be effected. If a channel exists solely for the purpose of advertising/sending ppl their script, perhaps it would. If you have questions, direct them to the proper source, DALnet. You can also sign up on the DALnet main email list for general discussion and questions where this was announced and has been under discussion: here Altho I would suggest reading their notice thoroughly so you understand exactly what they have already said.

Personally, i applaud DALnet and hope that all channels will continue the spirit of the change by not allowing ppl to sit idle in their channels solely to spam their fservs.
