You mean that's why some of my very favoritist PC members disappear and reappear like magic? Sometimes with new names even!
I cannot vouch for your favoritist PC members... but it isn't unusual to have someone try to circumvent policy... However... I am quite positive the powers that be here can keep track of their targeted individuals and determine if they are posting under a new nic... and deal with them appropriately. I have no argument with that. I do like to debate/argue though...
