It was reported by a freenode staff @Jesopo on IRC:
11:48 <jess> does anyone know much about CBNGRelay 11:50 <jess> there's a bot on freenode coming out of nat.openstack.eqiad1.wikimediacloud.org 11:50 <Majavah> that sounds like something related to ClueBot NG 11:50 <jess> and it's creating flood warnings 11:50 <jess> (a LOT of flood warnings...) 11:50 <arturo> oh, that could make sense 11:51 <jess> there's a way to stop it making those flood warnings without making the bot stop what it's doing, but i think i'll need to talk to whoever runs it
Potential fix:
11:57 <jess> the info is: that bot will stop making flood warnings on freenode if it has voice (+v) in the channel it's talking in. the channel already is configred to give voice to users logged in as CBNGRelay, but the bot is currently CBNGRelay1 and isn't logged in as CBNGRelay
