Worst thing I've seen recently from Blizzards side was the Blizzcon Stream pet redemption email. Actually it was not Blizzards fault but the streaming company.
They send out an email with the link text "blizzcon.com" or similar site name. But the link clearly went to an ".il" (Israel) domain. I actually thought it was bogus, and Thunderbird flagged it as phishing as well. I posted a warning on the Blizzard forums but was told it was in-fact the correct email
