In which way will siding with peace stop the messaging problem? If they were really in the messaging problem, they could of easily take care of it by a personal request to Stickmen, and maybe a public announcement warning other purple alliances not to do the same. But they arrive on the forums finely talking about their neutrality, only to reverse it in nothing more than petty revenge against the slight made by Stickmen.
The whole problem was about unsolicited messages, until Avalon's' decision to participate in the race, which caused all further discussion regarding PU (which is being a bit stretched, I agree, but not completely unrelated as of now).
