Again? There really needs to be a safeguard here. Both times this has happened it reeked of griefing.
We had a dev discussion the day it happened, and concluded that religions need the same defense realms have against Judges doing similar (it just requires a bit different coding work to make it work with guilds, not realms). You cannot kick more than 1/5th of religion in a two-day period. How long it takes for someone to implement, I can't tell you. But I can tell you that for every bug and approved feature, the best way for it to not be forgotten is to put it on the bugtracker. Which I know you are already good at, but public forum with other readers and all.
