ZOS_Kevin, the recently new Forum Manager of the Official ESO Forums, in response to a forum thread stated:

  Hi All, we wanted to follow up on the post here and the general sentiment about asking/discussing PvP in chat during livestreams. We agree that noting terms like "PvP" and "Cyrodiil" should not be timed out when players ask or referenced the topic in our livestream chat. The moderation shown in the clip was a bit heavy-handed. 

We have talked about this internally, updated our moderation training, and made sure everyone is clear that conversations around core functions of our game, like PvP, should not be timed out or banned.

Please keep in mind that spamming those terms (or any terms) will be treated differently, as the action of spamming is disruptive to the entire experience. We understand that spamming was not present in this clip, but we want to highlight that there is a clear distinction between asking about/referencing PvP and spamming text blocks of the term.

Thanks everyone for following up on the video and the concern around moderation. We will continue to strive toward better moderation overall and appreciate your feedback.
