Of course. The people are trying to extort money from Blizzard. Doesn't hurt as much when content is a bit stale. People will just say oh well and come back tomorrow. Today, it's full of returning raiders who will complain, moan, etc about how Blizzard failed to do something to prevent it, while others will ragequit and cancel their subscriptions until the next expansion.
It's telling Blizzard they need to buy some protection...which is wrong because it means they will continue to face this threat.
