Or children! I, personally, have known two 16/17 year old janitors, and I was the /po/ janitor when I was 15. IT IS A MYSTERY.
Yes. The whole 4chan moderation team is fucked up. Who knows? There's too many users and too little roles. I think that good tripcode users should be made janitors. (This has been done in the past with moderate success).
Look at the number of reports, I guess. But generally, mods/janitors should be liberal. I mean it's fucking 4chan for Christ's sakes.
