Just something about your script:
Try lowering the flood time for regular commands
on *:TEXT:!DMbrandon:#: {
if ((%flood!DMbrandon) || ($($+(%,!DMbrandonflood.,$nick),2))) { return }
set -u120 %flood!DMbrandon On
set -u120 %flood!DMbrandon. $+ $Nick On
msg $chan If you enjoy DMbrandon you can subscribe to him at http://www.youtube.com/dmbrandon Follow him at https://twitter.com/juiceDiem and also watch him stream everyday from 7-10pm US eastern on http://www.twitch.tv/smitegame $+
}
I'd say to change
set -u120 %flood!DMbrandon On
to something a little lower
set -u10 %flood!DMbrandon On
this will allow everyone to use this command after 10 seconds but a single user cannot spam it until 2 minutes passes every time
