As a reminder, posting about account actions is generally not allowed on the forums and it is not a means to appeal or resolve issues. This was resolved privately between this player and us after the video he posted this morning.
Just pulling back the curtain a little here but long story short, this was a mistake on our end. This player actually has a great history of reporting issues with us that they've found, and they wait for us to verify it's fixed before they put the videos up. This was a case of not everyone internally knowing this was happening and that the exploits he showcased were fixed, before the videos were posted.
The videos being posted are an example of great bug reporting in how detailed they are in showing how exactly to reproduce an issue. This is something Ion hit on in the last Q&A where he talked about the Quality Assurance team and how they have to reproduce issues that players report to us. Sometimes reports aren't detailed enough and it makes it a little harder to figure out some issues.
I just want to end this by plugging the correct channels to report bugs in.

Previously explained that e-mail is for questions about joining the MVP program not feedback and complaints.
Code not being enforced is entirely up to Blizzard as you can see here they're keeping threads open that violate forum rules as stated by you and the lounge.
