At amazon in 2010, it started with a meeting invite that was accidentally sent to everyone. The meeting was for the Amazon Wallet team for whatever work they were doing at the time. A reply-all storm ensued, and despite several people asking to stop hitting the reply-all button, it continued for several days. The management had to chime in and sometimes threatened people with punishment if they continued participating to the reply-all storm.

If you ignored the conversation you may not have seen it, but most reply-all storm ended up with someone saying something the line of "we don't care about your wallet".

Anyway, asking people to stop hitting the reply-all button is far from being the latest reply-all on these kind of things...
