We, as a site, don't do petitions. I'm not gonna speak for the boards I don't mod, but I'm not going to let that change for the recent Toonami event.
Everyone is invited to voice their opinions towards CN in the Toonami Thread at the CN Board. That should concentrate the posts in a single thread and I don't see reason for any others to be made. So far discussion has been polite without much need to intervene.
I'll let the AS mods answer for that board, but things won't change on the CN Board.
