Shouldn't BTC be taking some emergency measure and decrease mining difficulty significantly temporarily for a start?
Not really, since BCH will go up 400% tonight no need. But it also looks like BCH has now failed in it's takeover bid anyway.
But people who own mining pools who are not arseholes could probably up their game to clear transactions maybe.
Not sure anyone can really do anything about people maliciously spamming the network can they? Genuinely asking.
