Blog pingbacks in mod queue

Hello

On Weds (28th June) we published three blog posts in the community as part of one of our product launches. These blogs saw a decent amount of traffic, but our mod queue has also seen over 200 entries for pingbacks in 2 days since, which is hammering my inbox via notifications. We set blogs to have comments moderated because we used to get hammered by pingbacks and I am wondering if there is anything I could, or even should, be doing to prevent pingbacks from appearing in the mod queue?

Thanks

Oli
