Ircd spam filter

[Jack L.]

Imagine what would happen if an ircd filtered every private message that went through it, word by word or character by character, how much cpu it would take to process each private message. If you have a large irc network and a large amount of people chatting continuously, the irc server would lag to mars trying to filter out each private message. If you think about the efficiency side, it would be better if the ircd not handle message filtering and leave that up to some irc bot or some irc service. ircd filtering private messages is not practical.

Spying into people's private messages is not what an ircd is written for and personally, I would not want my private messages filtered in any way shape or form. Private messages are exactly what they are, private. Filtering everyone's messages just because some spam bot decides to ruin everything is not a good reason. That is like filtering everyone's private emails to find that spammer. It is unfortunate that people use irc to spam, but filtering private messages is not the way to go.
