A lot of IRC clients implement their own message rate-limiting logic to avoid triggering server-side flood protection, by e.g. sending a message every 2 seconds after a threshold, rather than dumping all of it at once. While this avoids flood kills, it is more frustrating for other users. Who likes to receive one line in your long message every two seconds, interwoven with other people’s conversations? I don’t have these server side limits on my own network because I don’t want to encourage this ridiculous delayed queueing behavior. I’d rather see 200 lines go by immediately than have them slowly and painfully clog the channel for 3 minutes. I find these sorts of limits to be an act of evading detection rather than anything truly helpful.
