In a post over at CCN.com it was noted that an attackers assault was carried out through Mailgun, a third party software provider. Reddit uses Mailgun to process platform-wide email services like password resets. They were able to gain access to Reddit's password reset emails. Users started noticing Bitcoin tips were disappearing after password rests.
Steemit and it's blockchain based structure would seem to be a great social news alternative to those living on the blockchainless web. I think with time the world will come to realize the Steemit model is the future.
