I keep getting messages containing links to pornographic websites. How do I stop them?

These links are usually sent from clients or "bots" on a virus-infected computer.
They join channels at random and send these messages to every user in the channel. An effective way of preventing this from happening is to set usermode +R, which blocks unauthenticated users from sending you private messages. You can do this by doing /MODE nickname +R
Another alternative is to set channel mode +r. This prevents the bots from joining the channel, as they are unauthenticated, which stops them from acquiring the channel's nickname list. It is then impossible for them to message individual users, as they do not know the nicknames of the users.
