Reminds me of working at a big company where everyone gets openly cc'd on an email and people start using reply-all and soon everyone is bombarded with ridiculous replies. But then the funniest part comes when higher-ups start replying all to say "stop hitting reply-all!", as if that somehow helps. I understand the temptation to say something, but sometimes you just have to let it blow over because anything you do will just make it even more obnoxious
