Since when is saging considered flooding?

The spammers and trolls are taking over /s/ as of late and I can't sage more than once every 5 minutes.  What the fuck?  The text body is different, so why is it being detected as a flood?

>sage post: 10 minutes

The sagers come out the worst in this. Sage didn't even do anything (of value) before. Why doesn't Moot just get rid of sage, because it's been virtually fucking useless for two years now.
