Could it be that the general ban on substantive polling in ATMB is to avoid every “why did I get warned” thread and the like turning into some sort of referendum on mod action? That when the subject comes up and they all lock electronic eyes with a look of ‘fuck that noise’ and reject the idea. A ha hah hah, you got me, though, people can talk about it already, so it’s not really a thing. Okay, you got me; there is no distinction between a thread with and without a poll and no one would make anything out of it. Gotcha.
Anyway, the presumed paradox doesn’t really exist. You can discuss any mod action, just not set up a poll about it. You can set up a poll outiside of ATMB, but not for discussing/weighing in on mod activities. There are easy examples of ATMB threads that could lend themselves to polling, but because there is a large group and of them where it wouldn’t be a good idea, preventing them all avoids the “why did you let sally poll this but not johhny that?!”
