I don't think I've ever been this upset by an abuse of spam before. This is the worst kind of thing that could have happened as a result of HA's tournament being sent to so many people.
I had a couple of messages that are now gone forever, deleted because of these spam messages. It will now be difficult for me to facilitate my clan work and play strategically in tournaments based on messages I've received from participants that are now gone.
Worse, I will potentially lose more important messages in the future because at any time someone can start a holy spam war and others will begin sending responses saying "stop it, I hate spam." Not to mention you, as the spammer, seriously abuse a list you didn't create.
Spam Is Not Cool.
Spammers should be punished.
