Sure, as long as the vols don't post >>>/gulag/
and delete posts at any whiff of meta discussion. People replying to a banned post with positive or negative feedback isn't by itself a "discussion." It's pretty easy to make a thread/post here and reply to such a post there with a link to here. Just type >>>/gulag/2601
or whatever the post number is and you can link from other boards. If someone has more nuanced to say than MODS=GODS or "that didn't warrant a ban" they can post about it here and link that in a reply to the post. Big problem with /gulag/ is lack of activity. If meta discussion goes here, there should at least be crosslinks from the place being discussed. That way you will get more traffic here and the people who are most interested will see there's a discussion happening. If standard procedure is simply "take it to /gulag/" then at best people have to look for the discussion here and at worst it disappears into the void.
This seems like a reasonable approach if Vote 1 passes.
