Autoresponders gone wild - edg.io (or Meta), make it stop

I'm on my last full day at StackPath, and a couple of autoresponders are making my work email even less usable than usual. It would seem G-Core Labs S.A. (ASN 199524) sent a peering request cc'd to every address they could find relevant to @INEX LAN1 Dublin, and the various autoresponders have been duking it out since about 5:49am Eastern.

The only one still emailing everyone several times/minute is support@edg.io. If anyone knows someone at edg.io who can make this stop, please suggest they do so asap.

It would appear noc@meta.com is also involved, but at least Meta's autoresponder has the good sense/programming to not spam the entire recipient list...but it likely playing ping pong with support@edg.io.
