205:(see below). Since some clients separate the private conversations into another window, each new message could open a new window for every new user a message is received from. This is exploitable by sending messages from multiple names, causing the target client to open many new windows and potentially swamping the user with boxes. Sometimes the easiest way to close all the windows is to restart the IRC client, although scripts (client extensions) exist to 'validate' unknown nicknames before receiving messages from them.

This is the simplest type of IRC flooding. It involves posting large numbers of posts or one very long post with repetitive text. This type of flood can be achieved, for example, by copying and pasting one short word repeatedly.
