This will trigger on any /msg or /query from a user, send them the lines of text, close the query window, then ignore them for an hour. Add more lines of text as needed. You can make the ignore permanent by removing the -u3600, or change the time which is in seconds.

Code:
on *:TEXT:*:?: {
  msg $nick Text line 1
  msg $nick Text line 2
  close -m $nick
  .timer 1 1 ignore -u3600 $nick
}
